I'm using some RUT955 (V6.7.4) for connecting PID on our supervision system.
the connection between the router and our system is using ipsec tunnel.
the connection between the router and the PID is using serial link.
All the router's have the same configuration except for their Ip adress.
since two days one of the router can not be connected to the supervision.
it seems like the serial over ip does not work anymore.
I can see that the router is not listenning en the TCP port i have programmed on the router.
I have done several test like disable/enable serial configuration, modifying the port, .. and the router never listen on the programmed port anymore.
What can i do to solve this problem?
