VPN Client to PIX515 inside network and dmz

[adamson67]

I am having a problem browsing/pinging to resources on the inside network and a web/ftp server on the dmz after authenticating with a Cisco client/IAS-RADIUS. I have attached my config below. Any help will be appreciated.

No it didn't help. I am still having a problem browsing/pinging to resources on the inside network after sucessfully authenticating with a vpn client to IAS radius.
From the inside network I can ping the 172.16.100.x ip address that is assigned to the vpn client though. Can you see if you can help resolve this first before I put resources on the DMZ? The full config is below.

Attached are the stats for the connection. They look ok except still can't browse. Maybe you can find something here.

HI.

It may be a routing issue.

What is the default gateway of internal clients?

The router 172.30.1.1 should have a correct route to the 172.16.100.0 network (VPN clients) that will point to the pix.
The internal server might also need a correct route, depending on your network configuration.

Or you might wish to use RIP internaly - but static routes are better in most small network scenarios.

Use syslog messages at the pix to get some more info.
