I have 2xSG210 in HA, after I upgraded to 17.1.3 MR-3, VPN got up but all incoming services did stall for a very long time and some services had no reponse. I found out that BOTH my WAN links (Normally running Active and backup) was running Active / Active, so traffic flowed over both connections, which was not the case before the upgrade. After I changed the "WAN2" to Backup in Type, all worked again:
Any others seing this?
