I am using following tutorial for connecting IPSec/L2tp client server.
My test network is as follows
Server Linux PC 172.16.10.199
<-->(LAN 172.16.10.254) ROUTER (WAN 22.214.171.124)
<--> 126.96.36.199 Client Windows XP PC
I follow all the steps in the tutorial. I can see the ISAKMP packets at Linux PC
But server not responding. I checked all conf files and PSK but servernot responding.
I checked the /var/log/secure, its showing as follows:
packet from 172.16.10.199:500: ignoring Vendor ID payload[Vid-Initial-Contact]
packet from 172.16.10.199:500: initial Main Mode message received on 188.8.131.52:500 but no connection has been authorized.
Please, help me where I am wrong.
Thanks in advance.
