Hope this is the right spot...I've done searches and foud posts that are close, but no solution that has worked for me....
Summary: My firewall is a PIX 506E. The other company is using Cisco routers on both ends to maintain the VPN. I have no access to their equipment.
I have a vendor that has put a Cisco VPN device behind my firewall. They originally told me to make sure I could ping 4 IP addresses (they supplied) and all would be fine. I was able to setup my firewall to allow the pinging to the internet. However, now they say I am reaching their end of the VPN, but my firewall is blocking IPSec.
What do I need to do so I can allow this traffic to pass through my PIX?
