Hy All!

I have a Samsung Galaxy S22 Ultra with factory Android 14 and ASUS RT-AX56U with ASUSWRT-Merlin RT-AX56U 3004.388.6_0 firmware.

I enabled the IpSec VPN server and I can't connect to it.

ipsec.conf file:

I have try out it on LAN and WAN with RSA, PSK and MSChapV2 method, nothing is working.
 
I'm connecting with Android 14 without issue on stock. Only difference I see in the config files is that mine has my explict wan address instead of the asus ddns address in various locations (config file created automatically from the gui).

My ISP work with dynamic IP. I masked out my real IP in the config file. What method do you use to connect to VPN?

I just use the client built into Android. Attached is the config screen.

What does the vpn log show? Can you share a screenshot of your ipsec config page?

Can you show the vpn log when you attempt to connect from outside your network (from the wan)? There should also be lots of other attempted connections from the Internet there as well (lots of uninvited folks knocking on your door).

I have attached my vpn log file when I successfully connect. Hopefully it will help you or others debug your issue.

I change loglevel for charon daemon, This is the first problem:

Feb 6 15:35:22 03[NET] received packet: from mobile_wan_ipv4[36640] to 192.168.1.1[500]
Feb 6 15:35:22 03[NET] received packet from mobile_wan_ipv4[36640] to 192.168.1.1[500] on ignored interface

After this I removed br0 from ignored interfaces. Second problem:
