Ashwani, The IP used to connect to the VPN is called the "VPN Peer". Of course Kannel shouldn't try to connect to that one, since it's the IP used to establish the tunnel.
The other IP (or IP's) are called the "Encryption Domain". If you have established your VPN well, all traffic going out on your host to the enryption domain should be directed through the tunnel established over the vpn peer. Looking at your logs, there are many issues that could end with a "Connection Timed Out", but most probably is related to a VPN configuration or firewall issue. The first thing to do is to check if you're able to connect to the SMPP host/port on the other side by using other means of connection. I'd suggest you to try using telnet to the host/port on the other side, since most operators block ping from external IP's: telnet <smpp host> <smpp port> Keep in mind that if you're host have more than one IP, you have to use the same IP as kannel. Usually, the first interface on a multi-ip host is the one used to establish connections (you can change that on kannel by using the "our-host" directive on conf files). If you can establish a connection using telnet (I don't think you will) then the problem is on kannel. The other "suspect" could be a firewall configuration on either side, check your setup and ask your operator about it.
