Archer C7 (US) v2 locks up with Wireguard

[Lantis]

The lock up is almost definitely a routing issue. It doesn't know where to send any packets.
If you can get it into failsafe mode and then

Code: Select all

cat /etc/config/network
cat /etc/config/firewall

You'd have to throw away the keys from the files before posting

I wonder if this happened to me when using OpenVPN?

Finally back to trying this Wireguard on V13.0. Now have screen shots, too.
1. Today I unbricked my Archer C7 v5 by doing a TFTP recovery to TP-Link firmware.
2. Then I loaded a factory version of Gargoyle v13.0
3. I set a few of my network configs (not many, as I expect to be need resets anyway)
a) Wan - DHCP from house router
b) Lan - Server, with Wifi 2.4g, Wifi 5g, Guest 2.4g
c) Lan DHCP - 172.16.24.0/22
d) Lan IP - 172.16.24.1
4. I enabled Wireguard server
a) Server with generated keys
b) Internal IP 10.64.0.1
c) Internal subnet 255.255.255.0
d) Port 51820
e) Allow clients to communicate with each other, Allow clients to access Hosts on LAN, use WG for all client traffic
f) Save, no problem
5. Configure New Wireguard Client, click Add
a) client name JeffsiPhone
b) Internal IP 10.64.0.2
c) 172.16.24.0/255.255.252.0
d) public key
e) Save >>>> LOCKS ROUTER

More info: I can't get back in with a Failsafe boot. Your comment that it is some routing issue seemed right, so I tried a new approach, access the router by its IPv6 address. It worked! Now I can see any of the settings in the GUI. I still can't access by SSH or Telnet, though, in part because I don't know how to use them with IPv6.

SSH over ipv6 should be the same, no special tricks.
If you can get in and look at the routes, look at the firewall and network configs, this would all be helpful
