19.7 Legacy Series / OPNsense 19.7.7-amd64 // Multi-Wan Fail-Over: UDP working, TCP not
« on: November 27, 2019, 09:37:52 pm »
Hallo everyone
I have setup Multi-wan according to the documents in Wiki.
WAN1 & WAN2, both priority 255, are identical except for IP & DNS addresses
WANGROUP have WAN1 as TIER1 and WAN2 as TIER2 with Packet Loss & High Latency
All Lan rules point to WANGROUP as gateway except for the proxy & DNS rules
Sticky Connections is ON, Shared forwarding & Disable force gateway is both OFF
WAN1 & WAN2 NIC's are TP-Link Gigabit PCIE TG-3468 & both routers are Huawei B618
When WAN1 goes down, UDP services like VOIP & VNC switch to WAN2 and continue to functioning, but TCP services like mail and web browsing stop to function. What I have found by accident is that when WAN1 is down and the WAN1 network cable is unplugged, all TCP services start to function via WAN2 and when the WAN1 network cable is plugged back, TCP services stop to function.
Is there a setting that I miss somewhere or a rule that I need to create?
Any pointers will be highly appreciated, thank you in advance
