I thought we were talking about NAT routers, like the ones sold by
companies like Linksys.
Note that the OP didn't say "routing table", he said "router table",
i.e. some configuration table on the router. A router that performs NAT
generally has a table of static translations, which may contain address
translations and/or port forwarding entries.
