Hello,

I just replaced a Cisco 1941 that was running BGP and advertising a whole class C block to two ISPs with an EdgeRouter Infinity. There is an ASA firewall behind the 1941/EdgeRouter that is doing the NAT translations for this class C block. The Edgerouter WAN interface has only 1 address assigned to it.

In the 1941 there was a guest wireless network setup on it. I am trying to configure the EdgeRouter to also have this guest wireless network. I setup an interface with a 192.168.22.1/24 address, configured DHCP for that network, and created a Source NAT rule for the 192.168.22.0/24 network to translate it to an unused address in the block. Am I going to have to add that unused address in the Source NAT rule to the WAN interface also? Do I need to setup any routing or firewall rules?

Thanks
