[f-nsp] Serveriron xl - Def GW for real servers?

[Robert Geller]

In order to use VE interfaces, you have to turn on IP forwarding. I have 
done this on many XLs.

Also, keep in mind when source-nat'ing, you will need to add more than 1 
server source-ip if you have more than 65K connections.  The XLs only 
support 8 server source-ip (major gripe of mine).  You can configure 
more than 8, but only 8 will work.

Cheers
