I've added an issue on redmine: https://redmine.pfsense.org/issues/16354

@greatbush while I have about 3 minutes here do you realize that windows machines by default will not allow pings and such from outside their own subnet to come in? Just trying to rule out any issues that you might have with Windows firewall on those machines..

@ThePowerPig So add an additional rule to allow access to internal subnets (best to create an RFC 1918 alias for this purpose), but at least for the IPs you want to access from the device in question, and move this rule up above of the policy routing rule.

@Nicholas97 Sticky connections are not enabled. Gateway status is fine. Weights for each LAN are set to 1 which should be fine for 2x gigabit connections and total bandwidth used of less than 1gbps. Will look at the logs but will have to figure out what I'm looking for ... will report back. I have read the multiwan load balancing docs pretty well and searched the forums here before posting this originally. Unless there are other pfsense forums you're referring to?

@Proton retro bowl said in VoWiFi slow failover when using GW Groups: I have theese GW groups: [image: 1751568295930-e947b6a3-6853-4534-a448-05e780e72965-image.png] I have a statis route for Mullvad GW to exit through starlink: [image: 1751568352001-ebd2ec98-90a0-4646-9af4-8ddfd609bb32-image.png] On both Mullvad GW i have: [image: 1751568423315-8f24a410-ce6b-430f-acb9-ce97a7ff84b0-image.png] The same for DOME GW. Default Gateway is group : [image: 1751568497527-adb3cbe1-1276-48a2-a07b-e29b797d6610-image.png] and the othe rgroup lookes like this: [image: 1751568531048-5cfa03be-dd61-4bb0-b562-c4fc9dc6c5b9-image.png] , I have also set: [image: 1751568573300-ea0c1c09-dd93-4722-9479-dc0f019f06ea-image.png] And i have my floating rules like this: [image: 1751568631542-a86219e7-b85f-4fb0-a8df-374beaeb0f04-image.png] Including QOS settings. The idea is that when the boat is near land the DOME GW is avtive and is top priority. VoWifi also exit there if possible. So - when we only have Starlink - i force all VoWiFi traffic through WG GWs to always have VoWiFi work even then starlink has exit node abroad (get norwegian ip = allowed ViWiFi). So to my question: When both Dome and starlink is online, i can call using VoWiFi, no issues. But when Dome failes, it takes several minutes (5-6) before the mobile again can call. or get a call. Why is this? I know we are using UDP trffic and STATES here and that a cell phone can have a delay before he checks and reestablishes VoWiFi again, but is there something i can do to make the transition to WG GWs through starlink faster? How can i kill the STATES faster? I have also tried sloppy states and state timeout set to 25, but with same result. Suggestions? THX! You can try implementing a script that automatically flushes states when it detects a Gateway change, as this will significantly reduce the switching delay. The problem you are experiencing is that VoWiFi UDP connections still hold the old state, so the device takes time to check and reset. When the state is refreshed immediately, VoWiFi will reconnect faster and avoid the current 5-6 minute wait. Additionally, you can also consider reducing the state timeout value further or enabling the flush states on gateway down feature if your system supports it.

To clarify what does work: What works is that from either site, a client device with an IP of 10.40.x.x is able to traverse the tailscale tunel to the other site by using the 10.65.x.x addresses. However, no device in this 10.40.x.x subnet can get to a 10.40.x.x IP at the other end. I realise that I am NATing the outbound connections rather than directly routing them due to the limitations of pfsense, so I am thinking I need to translate the 10.40.x.x subnet on the way out of the site, but nothing I have tried seems to work so far.

@sgw said in splitting a subnet, moving from LAN to WAN: When I try to ping an IP that has not been used before and in the LAN-part (10.96.25.128/25) from "upstream"/"outside", it gets logged on the pfsense as blocked by the firewall (which is OK in terms of fw-rules). So the pfsense seems to take over traffic pointed to these IPs. Could I modify NAT-rules maybe? Is that related to Outbound NAT? Could I somehow exclude It seems that the lower IP range ist routed to pfSense WAN address. If so, you can do nothing. You cannot use the same IP outside pfSense, because pfSense was not able to route the traffic to the VM, since the subnet is defined on the LAN. You only option would be to use an IP of the upper /25 on the VM and forward it on pfSense. But note that doing this also requires an outbound NAT rule (masquerading) for the forwarded traffic.

@pwood999 Indeed. I also run dual fiber links (on different physical fibers, with different building entry points) for resilience, not speed. Plain failover is enough for me too. But issues are issues and should nevertheless be fixed.

@cust You don't need to wait anything. You can apply this patch via system patches package, just use commit id 62b1bc8b4b2606d3b20a48a853ef373ff1d71e26

Resolved by implementing BGP peering over IPSEC.

Thanks again for the video. It solved my problem. If anyone bumps into this thread in the future, the static route showed in a screenshot above here was correct, however here's what I did wrong: On site2 I had set "IPv4 Upstream gateway" in the interface config to the gateway on site1. This makes pfsense NAT the traffic instead of routing it. Here's a timestamped link to the video where this is explained.

I really wish I could do the same here. I get some false positive failovers because the single IP monitor becomes offline, but the gateway is working fine... Gateway 1 monitor 8.8.8.8 Gateway 1 monitor 1.1.1.1 Gateway 2 monitor 8.8.4.4 Gateway 2 monitor 1.0.0.1 Gateway 3 Then prioritize them and route following this order.
