I have one PIX 506e, on inside lan there is one PC client, on this client there is SSH Sentinel VPN Client software for connect this PC to a Remote lan protected by Zyxel Router/firewall.
When I activate Sentinel software,
VPN Tunnel goes ON but the taffic doesn't work, for example is not possible to ping any host.
If I remove PIX 506 and I connect PC directly to the Router, VPN Tunnel goes ON and any host of remote Lan respond to Ping. Zyxel support suggest to verify Port 500 and port 68.
Cisco PIX log say:
305006: portmap translation creation failed for protocol 50 src inside:192.168.2.169 dst outside:88.xx.123.zz
