Home Hub routing table overflows.

Now I've got my Homehub embedded in my network I appear to be getting
the old Nat/routing table overflows causing the router to lock up
after around 48 hours.

Is this a known problem or is it just my usage which is causing the
problem. I have turned off the UPNP support as that did appear to
make a difference with the SKY Netgear, mind you that didn't stay up
for 48 hours at one go, so maybe it didn't..

Any clues, anybody else having the same type of problem?

Common problem for P2P users with cheap routers, Netgear in particular.
The answer is to limit the number of concurrent connections.

Already choking mine & that was the only thing that the SKYNET Netgear
did ok.

I'll play a bit longer but notice you are the first person to call the
Home Hub cheap (well mine was but...), in some circles they are
apparently raving about them (I know just before the men in the white
coats come to take them away)..

It a problem with the Speedtouch range in general with earlier v6 firmware.
Speedtouch 716WL and 780WL suffer the same issues

More like poorly configured/poor firmware than the price of the hardware
as such.

My 22 quid solwise may well have fallen over with the default firmware
settings as it only had a 512 conntrack max set - 1024 seems to be the
default for most routers, both I can easily use up. With routertech
firmware I have 3k as max and lower timeouts. Though it only has 8M RAM
I couldn't floor it when I tried, logging in is a bit slow when memory
gets low, but that's all I noticed. Wireless routers usually have 16M RAM.

If your router uses linux and you can get a shell then it's easy to
tweak, the HH is Linux but I am not sure it's accessible.

Limiting connections may help a bit, but if you forward ports and get
network traffic you can't stop incoming connections using up your
conntracks.
