@Sadiqus yes it seems strange, I did a test here now with a manual ipsec tunnel between an ER605v2 and an ER706W it connected without any problems. ER706W also has an ipsec vpn to a Cisco firewall so...

@Sadiqus ok, try deleting the tunnel on both sides and re-creating it if you haven't tried that.

@Sadiqus I have a few ipsec tunnels but it just works very strangely, you didn't answer whether you have a fixed IP or dynamic IP on the WAN.

@Sadiqus then i don't know, i see you have auto vpn, i've never gotten that to work. do you have problems with all vpn tunnels? do you have a fixed ip on wan or is it dynamic? have you checked that...

@Sadiqus check if you are using a hyphen in the VPN name, change it to an underscore , hyphens are no longer supported

@Pancho41 It looks like they have skipped ZTP, according to raodmap it should have been implemented in the 5.15.10 version in Q3 2024, but it may just be postponed :-)
