Hi,

I have Nortel client V04_65.30 behind the PIX 515E V6.3 (4) configured with
PAT (Only one public IP address available) dialing in to Nortel VPN server.
Nortel client, server and PIX are NAT-T enabled. PIX is VPN enabled (isakmp)
for dial in for mobile users. When I try do dial out using Nortel client
behind the PIX I get error message "server not responding". If I disable
isakmp outside and enable "fixup protocol esp-ike" Nortel client works, but
it is not solution as a I have hundreds of client who need dial in. Is there
any way that this can work?

Thanks,

John
