On our two sites, we are using PIX 515E and from these sites, one having remote access VPN server.We have no problem to connect remote vpn from public network,but could not connect from other site which is behind the PIX.
there is only PAT is happening from inside network.
Following error comes always " Error 721: The remote computer is not responding."
We also did some packet capturing at destination pix between source (remote client IP:126.96.36.199) and destination IP (remote VPN Server: 188.8.131.52) but we did not find anything wrong .
packet capture file attaches (VMON.pcap)
Could somebody help me out ?
