Nat Misses and Nat slowness

webmedia07 · ‎08-25-2007

Currently we have a dynamic nat rule and three static nat rules. Whenever the static routes are enabled, Lan users experience long route seek times, takes a long time for a page to actually start loading. Using show ip nat statistics, Hits:4644285 Misses: 70410. Are these misses related to this problem? If not is there a recommended fix to the problem? Thanks in advanced

I found something interesting today. The cisco router is using the interface FastEthernet3 which has no cable attached into it. We only have FastEthernet4 attached with a cable to the Lan. I searched throughout all of the cisco's config files and interface FastEthernet3 does not show up as an interface for traffic. Is this normal?
