Hi, I'm sorry if this sounds trivial. I've read the documentation on transporting traffics, but it seems that I still have no luck transporting traffics through multiple IPv6 addresses. Note that I setup transporting with IPv4 without problem. So I wonder if there's anything I've missed in my configuration that I have no idea about. With this example configuration : acl userA proxy_auth userA acl userB proxy_auth userB tcp_outgoing_address dead:beef:1:34b:0:11:49:1 userA tcp_outgoing_address c001:babe:1:21b:9:42:87:1 userB I assume that all traffics made by userA will be transported through given IPv6 address. And the same treatment will be applied to userB with different IPv6 address. However, no matter which user is used, all traffic is transported through one IPv6 address only. In above example, when userB is using the proxy, this user's traffics are transported through dead:beef:1:34b:0:11:49:1 and not c001:babe:1:21b:9:42:87:1 as expected. Need enlightenment. Thank you.
