I am having some issues with my cisco 877 as of late; it is hooked up to my adsl2+ line and also serves as a DHCP server internally. The only two things connected to it ethernet wise are a linksys wireless access point and an eight port gigabit switch to which all the LAN devices are connected.
For the past week or so it seems to be crashing at random; I cannot ping the router, and if I am watching the console I see it start back up. Upon logging in again and running 'show hardware' the last reload reason is unknown. I have tried to diagnose the problem myself but I don't know what to try any more - nothing seems to be wrong with the configuration, and there does not seem to be any special circumstances which cause the problem.
I have included a few files, including my running-config, so if anybody has any ideas to diagnose this further that would be great!
Also just noticed some entries in the syslog [attached] which seem quite interesting; NAT seems to be hogging the cpu around the time of a crash, not too sure how to go about diagnosing / rectifying this. I could put a machine in between the router and the rest of the network and use that as a gateway / NAT box, but that seems impractical, and is working around the problem rather than fixing it. Any ideas?
Yes the 1700 is more powerful. It may also be that the nat translations are stable in the network with the 1700 while the translations with Vuze "churn" more. Bittorrent tends to generate a lot of sessions that come and go quickly. It will also use up your available bandwidth.
You can limit the total translations or the translations per host using the "ip nat translations max-entries" command.
Hope this helps
