Peter, Is the entire /26 routed via the IP address of the VM TCP stack from the outside? If so, break up the /26 into two subnets (host addresses 65-126 and 129-190) and you have the necessary separate LAN segment addressing. It wastes some host addresses in the first subnet, but gives you 62 hosts in the second one, and you can subdivide further if necessary (a /29 is probably the smallest useful subdivision, with 6 hosts per subnet) .
Check http://216.239.37.100/search?q=cache:VoFvS3w2dbEC:www.kbeta.com/Ktips/classc .htm+subnet+mask+table&hl=en&ie=UTF-8 for a useful table of subnet masks and subnet values. You should also consider using a Linux stack to own the OSA. IMHO, this is a lot easier with Zebra than it is with MPROUTE. Less smoke will come out of your router jock's ears when they look at the configuration syntax. -- db
