I am trying to migrate our current L2L vpn connections from our VPN concentrator to be implemented in our PIX515e, I am having issues with other peer-side which I cannot bring up tunnel over public network, other side uses 3600 series vpn router. My local host is the one initiating the connection for this tunnel, but when we fire up the application or do a telnet test to destination host on pre-defined TCP port 8893 it does not bring up tunnel, other side indicates that I am not even hitting their gateway. I setup firewall logs to see conversation but I do not see in logs even getting to IPsec Phase-1 . The other side requests are that my local host comes to them with its unique public IP, I have static nat for my local host with public IP .. anything that I could possibly be missing. Attached is partial fw log and config. PIX ver 6.3(3).
