I am trying to initiate VPN tunnels to a number of remote sites using the Cisco VPN client. The site I am connecting from is behind a PIX 501 firewall.
I cannot connect to a number of these sites with the PIX 501 in place; if the PIX is removed, or if I connect to my ISP via dialup, I can connect to all of them.
All of the remote sites are configured for IPSec/UDP, and are using VPN 3000 concentrators... any suggestions as to what may be happening?
Thanks...
Rob
