I've re install everything, then first I define the Gateway and Route to internal subnets (Servers behind a different LAN Router), and works perfect with 1 LAN and 2 WAN (no special rules), but as soon as I modify the LAN Rule changing gateway to Multiwan it stops working. Then I add two rules, over default lan Rule to/from servers Subnet, and is working again.
Later I will try enabling squid.
