We are experiencing a strange problem where the router will stop accepting connections from the outside world. We can still ping the router, however we are unable to access any of the ports setup for port forwarding neither can we access the web management interface externally, while still available internally. I have tried disabling the SPI firewall and testing, and still no connectivity. The only Internet filter enabled is the IDENT filter. (Unfortunate that we are not able to configure a specific rule for allowing ping requests from our own network only, as well as a few other services.)
I have a suspison of what may be causing the problem, but I may well be incorrect.
I notice that when the router first connects, and get issued with its IP address it picks up a gateway address, a few seconds later it will then re-receive its IP address with a second gateway. In the routing table the first entry normally shows
GW IP 255.255.255.255 -- PVC0
I notice that the routing table duplicates this entry for both first and second GW IP received, not sure if this may be causing some sort of conflict.
Also their appears to be a bug in the time being used in the logs, not relating to the time on the router itself, although the date is correct. The time is not out by hours, but also units of 10 minutes, so not a time zone issue.
Any advice appreciated.
