Have an 1841 router with the following interfaces:
0/0
0/1
AUX
on the right side, believe it's slot 1, there's an add-on interface FE0 (shows up as 000).
Does this allow a multi-WAN configuration? i.e. can I use 0/1 for WAN1 and FE0 as WAN2 out-of-the-box or does this require additional licensing and/or another add-on interface in slot 0?
EDIT
Need a dual WAN configuration to do policy routing only (no load-balancing/HA) so I can send certain traffic out the WAN2 connection for policy/security reasons. Will be doing SNAT for the inside traffic going out this interface as well.

If it's just going to be routing, it doesn't really care whether any given network is a LAN or WAN. Three interfaces? Two WANs and one LAN will work just fine. No licensing required.
If you're going to be doing NAT, things become more difficult.
