I have established VPN connection between a Cisco PIX firewall (version 6.3(5)) and a Netgear Prosafe VPN firewall FVS114. The subnet behind PIX is 192.168.1.0/24 and the one behind Netgear is 192.168.2.0/24. The Phase 1 is up and the issue is that while 192.168.1.x can ping 192.168.2.x, 192.168.2.x cannot ping 192.168.1.x. Any ideas why this happens?
