#7410 closed defect (invalid)

random translation/port forwarding problems

Reported by: anonymous Owned by: developers
Priority: highest Milestone: Backfire 10.03.1
Component: kernel Version: Backfire 10.03

Description

Similar to ticket #2558 in behavior.

After a random period of time, some inbound translations ("port forwarding") stop working.

Example:

iptables -t nat -I PREROUTING 1 -i eth1 -p udp --dport 1234 -j DNAT --to-dest 192.168.0.5 etc.

The conntrack table is rarely more than maybe 10 entries. This is not a heavily used router, and bittorrent hasn't been used since I brought it into use.

Model:

Buffalo WZR-HP-G300NH

Other notes:

"ls /proc/sys/net/netfilter/*" hangs in the D state, system load skyrockets, and the reboot actually failed - I had to re-flash.

A fix would be great but a workaround would also be extremely appreciated - e.g., a change to a kernel tunable or adding more swap on a flash stick, etc. - anything.

I consider this to be a pretty serious bug like before - seriously hinders basic functionality of the router.

Does this issue still occur in recent trunk snapshots and 10.03.1-rc3?
