[Olsr-users] Route on repeater nodes sometimes break when gateway node reboots

[Teco Boot]

Is *the traffic* from same connection?
If so, the NAT state is gone after a reboot and connection shall be restarted. Smart gateway cannot fix all problems.

From the affected node, I can ping the gateway's mesh IP and also the gateway's WAN IP, but I can't ping anything beyond the gateway node's WAN interface.
