Hi all,
I hope I can get some help on this because it's driving me crazy!
I have a ER7206 v1 running the latest firmware linked to a OC200 Omada Controller, also running the latest firmware.
The ER7206 is using 2 WAN ports, each one connected to a different ISP router in bridge mode to provide Internet access, both WANs are enabled and should (not confirmed) provide access, I'm not using WAN2 has a backup link, I'm trying to have both enabled at the same thing (because I have one client that needs to go through ISP2 and the rest should always go through ISP1 but somehow this configuration is not working, issue for another ticket later on).
Have 1 site providing 192.168.1.xxx IP's for every client connected and I have a VM running Home Assistant within a Synology NAS with also several other services like Plex.
If I disable bridge mode in any ISP router and connect my NAS to it, have its internal DHCP to provide IP's to every announced MAC and then run a normal port forward within that router for my Plex or Home Assistant everything works just fine, if I reconnect everything back to my ER7206 I lose external access to anything.
To make sure things wouldn't jump IP's, the most important services/servers I created a DHCP Reservation and then in Transmission -> NAT -> Port Forwarding, I created the following rules:
So as before, any call done externally to my DNS/IP on port 8123 or 8126 would forward to IP 192.168.1.212:8123, unless I'm missing something which I'm not seeing, this should work but.. it doesn't.
like I explain above, if I do a simple port fw configuration on the ISP router (without bridge mode active), the exact same config works, but behind my ER7206 it doesn't.
Already tried WAN1 active, WAN2 disabled, or WAN1 disabled, WAN2 active but the results are always the same, cannot connect.
Hope someone can share some light on this.
Probably a few things that could be going on here, so let's try to narrow things down.
Also, Plex is not the simplest of apps, I suggest you debug your port forwarding issue using SSH on the Synology (that's a single TCP port). You can enable this in your Synology and then port forward TCP 22 from your WAN.
1. Now, how have you set up your dual WANs, are they in failover or load balance?
2. If you change your port forward rule to use just the primary WAN (so single WAN) does that change your behaviour?
3. Are you testing from inside or outside your network?
4. Does your ISP router have uPNP enable by default?
So let's start with those and see if we can get SSH working across the 7206, then we can expand to PLEX.
Also, here's how I forced an IP camera to always use one of the WAN ports, using Policy Routing:
Thank you for replying, let's see if I can answer all your questions.
btw Plex is one of the examples, for me the most important service is actually Home Assistant but one or the other run from within my NAS so..
now for your questions:
1- both WAN's are in load balancer mode with 1:1 Weight
2- I've tried all combinations, both WAN active and enabled, WAN1 enable with both WAN active, WAN1 enable with WAN1 active or WAN2 active (but never both), change the config to only use WAN2 and disable WAN1 access, none worked (which is what bothers me the most).
3- I use my phone connected to 4G/5G and try to connect to my HA or anything behind the routers.
4- both ISP routers have uPnP active but I can turn it off if needed.
