[vpn-help] Help with "Session terminated by Gateway problem" with Shrew Soft VPN client 2.1.7 needed

[KrishnaMohan Bandi]

Hi Kevin,

   Thanks for your reply. I have tried changing the configurations, but I am
still getting the same issue. I am sending an updated log if that helps.
I wanted to know one more thing from the configuration point of view if my
environment set up is correct.

I have a Sierra 3G Wireless modem connected to the Ubuntu PC. It has got
10.2.xx.xx IP address with netmask 255.255.255.255. On remote side, I have a
Sarian 3G router with internet gateway 10.3.xx.xx and 192.168.254.254
gateway (on the other side) with subnet mask 255.255.255.255.

Your help is highly appreciated.

Regards,
Krishnamohan
