Cisco 2621 to other subnet

Hello everyone,


My current setup is Internet-CableModem-Pfsense-Switch-Devices

Pfsense gets the wan's ip from dhcp. The lan is 192.168.1.1 255.255.255.0

What I would like to do is setup another network using a Cisco 2621. I would want to do Internet-CableModem-Pfsense-Switch<-PC's on 192.168.1.x 255.255.255.0
........................................................................... ........................................................................... ...........................\ Cisco 2621XM-Switch-PC's on another subnet. (I am open to any address and subnet)

Does anyone know if this is possible? I have tried setting up the 2621 using Dhcp on the side connected to 192.168.1.x (dhcp is on windows server 192.168.1.254) and it received an ip address fine. Then I set the other interface to 172.16.1.1 255.255.0.0

The router is able to ping everything on 192.168.1.x and is able to ping internet websites. However the devices in the 172.16.1.x network cannot ping past the 2621. (but can ping the router 172.16.1.1)

If anyone can point me in the right direction, that would be extremely helpful. Thanks in advance!
