We are trying to establish VPN tunnel between UAE(PIX) and Egypt(IOS) but we are facing the following problem when we ping from UAE(Internal Network) to Egypt (Internal Network)
Note: In this phase the tunnel is up for both Phase1 and Phase2
- The UAE Firewall encrypt the Packet and send it to Egypt IOS Router
- Egypt IOS router de-crypt the packet and send it to end host
- Egypt End host receive the packet from UAE end host
- Egypt End host send the reply packet to UAE end host
- Egypt IOS router encrypt the reply packet and after that we don't know what will happen to this packet but it did't reach to UAE firewall.
so please advice us since we are troubleshooting this issue from one week ago.
Thanks in Advance
