You have some ambiguities which make it difficult to respond. When you say "natted host", where is it coming from: 192.168.122.0/24 or the "1. network" (you didn't say what it's subnet mask was) or elsewhere? Which interface is "connected" (directly or otherwise) to the Internet? Am I understanding you correctly that the main routing table on this system has no default route? Although not much is sacred, I normally set up a system with a default route in the main configuration and use alternate routing tables plus rules to deal with the exceptions. Explain a little better what you're trying to accomplish in non-configuration terms, I'm confused by your configuration specifications. I also tried your negation approach for 'ip rule add ...' and got an error because bash decided that the negation meant that history substitution was requested.

However I need to have this working for 0.0.0.0/0 except 192.168.122.0/24. How should I implement something like: ip rule add from 192.168.122.0/24 to !192.168.122.0/4 lookup 4 Leroy Tennison Network Information/Cyber Security Specialist E: leroy@xxxxxxxxxxxxxxxx 2220 Bush Dr McKinney, Texas 75070 www.datavoiceint.com This message has been sent on behalf of a company that is part of the Harris Operating Group of Constellation Software Inc.If you prefer not to be contacted by Harris Operating Group please notify us.
