[9fans] Plan 9 IPv4 router

[smiley]

Hi, all,

Does anybody know if it's possible to use Plan 9 as an IPv4 router?  I
know you can export the /net file system to other Plan 9 boxen, but I'm
wondering about using Plan 9 to create a network appliance/router.  I'm
envisioning using Plan 9 to do things that Linux iptables does... route
packets, NAT, rate limiting, etc.  Could you, for example, stick
Unix/Window$ boxen on a LAN and use a Plan 9 box as a gateway?  Is there
currently any way to do such a thing?
