Multiwan, Rules and allowing only some outgoing ports

[ayacopino]

I am implementing a new pfsense firewall (1.2.3), and i need a failover and balance topology.
The users in my network will browse internet with the proxy squid installed in pfsense, so i want:

• Block all ports on lan, only allow browsing with squid (almost all users)
• To use only some ports (80,443) to a specific IP (to browse without proxy).

I follow multiwan 1.2 instructions and appears to only have three rules, do i have to added load balancing rule and failover rules to all the ports i want to enable?

Thanks,

Andrew. ???
