Model: Omada Software Controller (Linux)  
Hardware Version:
Firmware Version:

Since the omada controller - for no reason - does not support fqdn ednpoints in wireguard, I had to evade to ipsec site to site tunnel. But the ipsec tunnel limits - for no reason - the number of subnets to 5.

 

I start to regret switching to omada. Those limits seem arbitrary and not technically motivated. Solvable by just changing the input form.

if you need more subnets create another tunnel, use the same encryption and key

  @MR.S So I define another Tunnel on one end only with the same psk and local/remote id and same endpoint?

Hi  @MVZ_MUDr_C 

 

What's the model number of the gateway router you are using?

For ER7206 v2, you can try the following pre-release version:

ER7206 V2 2.2.0 Build 20250113 Pre-Release Firmware (Released on Jan 15th, 2025)

Wish you a happy life and smooth network usage!  >Get the Latest Omada SDN Controller Releases Here< >Experience the Latest Omada EAP Firmware<
