Forward skype through etherX

RouterOS Forwarding Protocols
1

Hi all

I’ve mounted a RB2011 in a small office who have 3 balanced ADSL using PCC and a dedicated-simmetric link (not balanced).

Everything is working fine, now I need to forward the skype calls through this dedicated link who is connected in ether4. (the load balancing is between ether1 and ether3).

how can I do this?

Skype can’t be identified, so you can’t specifically forward only skype. What you could do, is identify all the known traffic, and then forward “the rest”
