Sudden DNS Failure? - Mogul, XV6800 ROM Development

Hey all,
XV6800 owner, dcd 4.1.2, 3.42.50 radio, 1.35_002 pri. A day ago DNS stopped resolving. If I put a valid IP into the browser, the page will come up, but the phone just stopped resolving DNS (for all DNS requests from web, email client, etc). Does anyone know if I can check/fix these? I know under the #777 connection that I can specify primary and secondary DNS IPs, however even if I put working DNS server IPs in those fields, it still won't resolve. I'm assuming Verizon has their own, can someone help me troubleshoot/fix this issue without a hard reset?
Thanks much!

Network GPRS setups with Proxy

All,
Trying to figure out what is the best way to setup your network connections on WM6 roms. I'm currently a Tmobile user in USA. The data plan im on, uses a proxy server. So it created an interesting problem if any expert out there can figure this out. HEre goes:
network wizard creates : Tmobile Data, Tmobile mms, on top of the My work network (empty setting), My ISP. None of them uses proxy.
Ok then I went ahead added the proxy into Tmobile Data config then IE works, push mail works from mail2web. AOl emails,YAHOO emails, weather ...etc stops working cuz the proxy.
Ok I decided to play with network management settings like a lot people suggested: I picked My work network (empty setting) as internet, Tmobile Data as private network connect. Now AOL,YAHOO ...etc anything cant use proxy server works, but my IE and PUSH mail fails.
My question is are there ways to tie connection to each application? actually tie into each mail account.
I remember there use to be a skipping proxy cab somewhere, I'm willing to try that cab if someone has it. I just need proxy to be transparents to some mail accounts and maybe applications like HTC weather.
Thank you. Let me know if I confusses everyone.
All,
Ok i did a partial fix.
Changed all the aol,yahoo, accounts to use work connection.
push mail can only use internet connection which has to have proxy. now that my sync doesnt like it, will fail with unreachable sever during sync because of the proxy. More digging. I know there are more tmobile web users out there. anyone has other suggestions?

[Q] DHCP Lease IP Address Issues

Not sure if this belongs in this section or not. I know this is an ongoing issue with some Android OS phones. I just wanted to see if any other Atrix owner is having the same issues or if anyone has ideas on how to fix.
Problem
Network monitoring shows that your Android OS based phone is causing a problem on the campus wireless network.
Your phone is not properly communicating with the campus DHCP servers, which assign (“lease”) IP addresses to allow your phone to communicate on the campus network. Your phone contacts our DHCP server to obtain an IP address, and is given an IP address to utilize for a period of three hours.
During that three-hour period, if your device remains connected to the campus network, your phone should automatically contact our DHCP server to request a renewal of that lease for an additional three hours. If your device does not complete that renewal, the lease on the IP address your device is using will expire and your phone must stop using that IP address. At that time, the IP address is returned to the pool of available IP addresses that can be assigned to other users.
The problem we are seeing from your device is that it does not request a renewal of this IP address and it does not stop using this address after the three-hour lease expires. In some cases, we have even noted your device attempting to renew the lease on the IP address it was using well after it was expired.
As the IP address your device was using returns to the pool of addresses to be assigned to other users as soon as the lease expires, by continuing to use this IP address, your device will be interfering with others users who have been leased that IP address by our DHCP servers.
We have seen this issue from many Android OS based devices manufactured by a variety of vendors and sold by a variety of mobile carriers. As such, we suspect this is due to a bug in the underlying Android Operating System.
We do not expect that there are any configuration changes or settings on your device that would resolve this issue.
So there it is. I've read through some Google forums and even here at XDA. Any ideas or help would be greatly appreciated.

[Q] Why change APN?

I have heard of people here switching APNs, but I never really understood why anyone would do this. To make a long story short, is there an APN that I can use that will give my phone an external routable IP address? It doesn't even have to be permanent--I can use a dynDNS client. Are there any side effects that I should be aware of when switching APNs?
If I can switch APNs, what are all the settings? I went to the Add APN screen, and there are a bunch of settings there, and I did not know what to put in there. My current APN is epc.tmobile.com
(Optional reading here for why I want to do this. May give important insight???)
I was testing a new (to me) program on my phone, "Growl for Android". It allows the phone to receive notifications from a PC, such as "Server is down", or in my case since I intend to connect it to my home automation system, things like "Alarm disarmed", or even "Alarm is sounding". So, my PC runs continuous tests, checks, whatever, and if it detects something noteworthy, it pushes the notification to my phone. Or said another way, my phone runs a small server to receive notifications from a PC running a Growl client. The problem is, my phone does not have a permanent IP address. When I am connected to my WiFi at home, it does have a permanent IP address, but when I am just on cellular, there is no telling what the IP address is. So, dynDNS to the rescue. Well, guess what? That won't work either because the phone apparently has non-routable IP addresses (we are behind a router). I had heard in a forum for the Growl application that a different APN may help. So I am asking here.

[Q] Have to kill/restart Mail for corporate vs. home network

I know this may seem like a corner case, but I thought I'd see if anyone might have a recommendation on how to automate it. I have the default Mail app from CM7 working great overall against our corporate Exchange server. However, when I change networks from corporate wifi to home wifi or vice-versa, it stops syncing until I kill/restart the application. My guess is that this is happening because the IP address associated with the mail server hostname differs between the private and public networks and perhaps the running process caches the IP address? That's the only thing that makes sense to me given that it can restore the connection just fine if it loses and regains wifi, but if you change networks you have to cycle the process.
Any thoughts?

Work Wifi issues

Just wondering if anyone else has run into this issue. When I turn on wifi at work, I get an error that says "sign-in not supported". Our work wifi requires a username and password, both of which are used to log into the network. Just wondering if this is an issue with the device or my IT network set up?
WiFi at home with encryption works fine, and public WiFi's works.
I'm thinking this stems from the same issues we having reading and replying to Corporate Exchange emails. My Exchange requires a password on device, although the Gear S has the ability to set a pin lock the whole thing stems from Corporations not being able to have access to wipe the watch.
Well, you know the wifi work cause you can access internet at home and public places.
I would first ask the corp IT dept if it is ok for you to log in with a unauthorized device first to the corp network. Now days corp IT dept have very strict access to what device and who can access their network due to hacking/virus......etc. If you can the ok, then you can ask if the GS is capable of accessing corp email and how to set it up.
