VPN Problems with WIN2k Domain

I have a Pix506e, and I'm using the Cisco 3.6 VPN client. I've always been able to connect to the Pix fine. I just recently configured a Win2k server as a Radius server. It seems to also work just fine. The problem I'm having is access to the inside network. It takes about 5 minutes for me to be able to ping anything. After that time, I can ping the DNS server, and my workstation, but I can't ping anything else, including the Radius server that I'm authenticating through. I have about 5 pc's on the domain, and I'm migrating more soon. This might not be the correct forum, so let me know if I need to try to post this somewhere else. I've included the config if anyone can see a problem with it. Your help is appreciated. Thanks.

HI.

> sysopt noproxyarp inside
Try removing it:
no sysopt noproxyarp inside
And see if it changes anything.

Your problem could be related to a NAT or other filtering device between the remote VPN client and the pix.
This could be a router at client or pix side, a software firewall, etc...

> ip address outside ***.***.***.*** 255.255.255.0
Is this ***.***.***.*** a public registered IP address?
Or is the ISP router doing NAT?

Yizhar,

Thanks for the reply.

What exactly does >sysopt noproxyarp inside accomplish? I had someone else tell me before that I needed it in my config.

Yes the ip address outside command goes to a public IP. I thought I had it setup for PAT with a NAT overflow.

Thanks again for your insight.
