NAT: multiple subnets using multiple pools

[mattlal]

After reading through quite a few white papers and forums I have yet to find a definative anwer and or an example. Currently on our network we just seperated it into 5Vlans (10.10.0.0 10.20.0.0 10.30.0.0 10.40.0.0 10.50.0.0) But, what I am trying to accomplish is having each one of the vlans to have their own NAT pool of ~10-20ips ea. I can easily get it to work on a single pool...but is there a way to get it to work on mutiple pools [if so can someone point me in the right direction]
Thanks
Matt

I am afraid you can not do that. The problem is we can not qualify the ip nat inside command. For doing what you would have to have the following option:
Interface vlan1
ip add ...
ip nat inside subnet10

Interface vlan2
ip add
ip nat inside subnet20

Then you would probably correlate the nat inside with the
ip nat inside source list commands.

Unfortunatelly these options do not exist.

well..good to know I cannot add the vlan due to position of d-mark [run off a switch which only allows 1vlan per port]. If it was run off the blackdiamond [extreme networks] it could possibly be done..but in order for such would have to move 1/2 the network equipment.
Thank you for your reply, does help accomplish/solve that problem.

You can do it with a PIX and multiple global commands.

If you have a server you could use that for DHCP and have a different pool for each subnet. The server will give out an ip based on which subnet is came from.
