<html><head></head><body>It sounds like you forgot to turn on net.ipv4.forwarding. It's strange that you have two subnets, too; wouldn't you have to teach the router and all other devices about the two subnets?<br>
If you put virb0 on the 10/8 subnet what happens?<br><br><div class="gmail_quote">On February 6, 2015 2:51:19 PM EST, CrankyOldBugger <crankyoldbugger@gmail.com> wrote:<blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;">
