First of all, you need to exclude from your dhcpd ranges, because 253.2 is your server (by the looks of it).

Secondly, next time don't put your password in the question, it can be unencrypted (not easy, but do-able)

Thirdly, there is no real reason why you can't ping to your inside network from the PIX.

Just a few questions:
1. Could you ping from the server to the PIX firewall?
2. Could you ping from/to any devices within network?
3. Is email still coming in and out? Or everything does not work at the moment? (If yes, most likely there is a hardware failure somewhere on your network. It could be your switch or your server nic?)

Thanks for you response.

The DHCP has indeed been set but it isnt enabled. I use our server wich is indeed 253.2 to play as DHCP server with a range of 253.10-253.100
Ok on the password, I just changed the password on the PIX just to be sure.

Answers to your questions:

1. Yes I can ping/connect from the server to the firewall inside address without a problem.
2. No I cant ping anything when on VPN on the inside range.
3. The other functionality, such as our FTP, email and even the webserver are working as they are supposed to. The only malfunction I can find is this problem with VPN.

Could it be that the DHCP is on another server? Second a little weird addition, when I have VPN and I try to ping the first time I get a response - after that It times out.
I have restarted the PIX multiple times and reloaded the configuration just to be sure.

Ping isn't exactly a perfect network connectivity test.

I think a good test is to connect via www, ftp, and vnc (5900) to your server while you have the VPN connected.

See how you go.
