I'm faced with two cable modems from the same ISP, with the same gateway. I can't lagg(4) the interfaces, since specific IP's are bound to specific modems. So I'm wondering if using stick-address with a round-robin nat pool is really sufficient to do load balancing of outgoing traffic and not get into session problems with various protocols. Has anybody had similar experiences? -- Mel
