Hello,
Can't renew IP address in proxy server 2.0 with external adapter that optains IP address from DHCP. This is exactley the problem I have. I copied the description from microsoft site(Q252432). I applied the solution they have on their site, but did't help. I have to renew the IP every 48 hours. Please let me know if you have an idea.

Router: cisco 675

Did you try and disable packet filtering and see if the lease to the external card renewed? If it did then its packet filtering causing the problem.

I had this problem and tried Microsoft's fix Q252432 and it didnt work so I ended up creating thetwo packet filtering excemptions below. It worked for me and maybe it will work for you?

Try and add these two custom filters in your packet filter excemptions and see if it works:

1st custom filter
---------------------
Protocol ID - UDP
Direction - BOTH
Local Port - Fixed Port: 67
Remote Port - Any
Local Host - Default Proxy External IP Address
Remote Host - Any Host

2nd custom filter
--------------------
Protocol ID - UDP
Direction - BOTH
Local Port - 68
Remote Port - Any
Local Host - Default Proxy External IP Address
Remote Host - Any Host
