Hey cisco gurus,

Senerio:
I configured the 2950 switch with vlans 10-50. The fa0/1 is set for trunking. Also I have set all the 24 ports to different Vlans that corresponds to the VLAN settings on the 2621.
The trunk is connected to 2621 Fas0/0 and its sub interface fas0/0.1 set to "encap dot1Q". I have fas0/.01-0.6 set up for VLANS 10-50 with "nat inside" and also set the "ip helper-address xxx.yyy.zzz.ddd". For Fas0/1, I assigned an Ip address to it with "nat outside" & "no shut" command.

I have a DHCP server connected to fa0/2 on the 2950 and a workstation conncted to (fa0/5;VLAN 20) and (fa0/10;VLAN 40). I am able to get the correct DHCP address relative to the VLANs my workstations reside on. ALL is great.

Any suggestions/HELP?

What I would like to do now is to connect my 2621 router to the linksys firewall via Fas0/1 and allow my work stations on the diff. VLANS to access the interet and not allow internet access depending on what VLAN the workstations reside on.

I have some ideas of how I might be able to do this, but I am not sure of IOS command sets. Has anyone accomplised this?
And can anyone post up the startup-config for this kind of setup?.
Any suggestions would be greatly appreciated.
Thanks,

Is the port on the switch connecting to the router setup for dot1q. By default it will pick isl.
