VPN in asus er-ax88u

[JDV]

Hi. I used to run a vpn server on my asus router so I could access my network from outside. After an update of the firmware this isn’t working anymore. Here is the setup. I use a modem router from my isp (can’t change that) on 192.168.2.0 (router ip is 192.168.2.254). In this router I put the asus router in DMZ and also forwarded Udp 500,4500 to 192.168.2.11 which is the ip of the asus router. The asus router is on 192.168.178.0 (router ip 192.168.178.1). I setup IPsec vpn but it won’t connect. I tried to also forward 500,4500 udp on the asus router to 192.168.2.11 to 192.168.2.254 and 192168.178.1. None of them works. What am I doing wrong.

If it stopped working after a firmware update I suggest you go back to the previous firmware and check that it works again. It could be a bug in the new firmware.
