we've got an SA520 with activated Load Balancing for two ISP's on the two WAN ports. Both WAN ports are showing "WAN status UP".
The problem is, that every connection stalls after a few minutes (for example a download, a web radio live stream or an PPTP VPN connection). It seems that the load balancing is switching the lines permanently for all sessions, which doesn't make any sense. How can I configure an session based load balancing without binding protocols on a special WAN port?
