I have an issue with one of our clients connecting to our PIX 525 using the cisco vpn client behind a fireall.
The client is able to establish the VPN session but no data can be passed between the client and the firewall.
The same client is able to successfully connect and pass data when they connect outside of the firewall.
I have 2 questions;
1. The client has suggested switching to tcp transport from udp to resolve the issue. How do I configure a TCP session on the PIX 525?
2. Is there any other setting I should be looking at to allow connectivity behind the firewall?
