Title: 2 wan interfaces - 1 ISP?
Post by: wbrussell on January 15, 2012, 02:49:20 PM
I am trying to find the easiest path to reconfiguring my router.  I currently am using a static IP on the wan port.  This is coming from a ADSL router.  I am going to switch that ADSL router to a new ADSL2 bridge.  Looks like I have to create a pppoe tunnel interface and change all of my rules that have destination wan to destination pppoe.

I have a lot of IP rules in place and I am trying to eliminate changing all of them.  I would also like to be able to revert back to the original scenario if I need to.

Is there a way to utilize the dmz port as wan2 for pppoe and perform the same rules and routing if a connection was present on wan1 (ethernet) or wan2 (pppoe)?

I read something on interface groups that sounded like what I was looking for, but I don't want to open up a new can of worms if I don't need to.

Thanks

To implement

1) Interfaces > Ethernet > dmz, wan (both)
Uncheck "add default route ..."

2) Interfaces > PPPoE
Add your new PPPoE interface
Keep "add route ..."

3) Intrefaces > Interface groups
Make new group wans = wan1 + wan2pppoe

4) Replace wan to wans everywhere necessary

To revert, uncheck "add route ..." on PPPoE and enable "add default route ..." on wan

Thank you very much, Alexandr.  That looks like what I'm after.  I'll give it a try this weekend.

Everything worked but my VOIP phones after re-configuring.  Here's the rule that I'm using, switched wan to wans.

Incoming_voip Allow wans/all-nets --> lan/lannet (voip services)
outgoing_voip allow lan/lannet --> wans/wannet (voip services)
