goodmorning my friends, this is my situation: I have two debian servers with static IP connected through a site to site VPN OPENSWAN, everything works like a charm, I can ping the entire lan from any workstations and transfer performance is very good. But what happens is that randomly(it can be 2 times in a day or one in 2 weeks) the VPN goes down. If I launch /etc/init.d/ipsec status I got that the tunnel is up but VPN is not working. Only solution is to launch /etc/init.d/ipsec restart or on some cases I need to reboot the routers. Anyone have some suggestions? or at last I just want to got a log somewhere but I can't find anything useful!
local ip server left is 192.168.0.100/24 and right is 192.168.1.100/24
for my privacy public ip server left is 111.222.333.555 and right is 111.222.333.444
this is my ipsec.conf on left
