Hello ! I have a strange trouble with RV082. Situation: we have 4 RV082 connected as "Gateway2Gateway" to OpenSwan CentOS server, every RV has real IP-address and server has one too. 3 routers from 4 are connected and works fine, one of them periodically loose ipsec connection (pings from linux stops and we get "ping: sendmsg: Operation not permitted"). After pressing "Connect" it works again some time (5-30 minutes) and situation is repeating. All settings are identical on all routers, config of OpenSwan identical too for all routers. What does it mean and how to fix it ? Thanks !
