DSL-AC68U GRE Tunnel

[MHKalantarian]

Is your feature request related to a problem? Please describe. Every VPN protocol is getting blocked, so either I have to use v2ray or GRE tunnel and v2ray does not support router-wide routing, so I want to ask to enable GRE Tunnel feature on dsl-ac68u model

Describe the solution you'd like I've looked around and people said adding CONFIG_NET_IPGRE=m to config file enables it, but I have 0 idea where the config file is or where to look for it, otherwise I would've forked it my self

Pointing me to a direction or making a branch with this enabled would be awesome

Hi, Merlin comes already with (Generic routing encapsulation) GRE module available, so you do not need to reuild the kernel. What they told you is to set CONFIG_NET_IPGRE=m in the kernel config and rebuild it in order to create the module you see here below. Run the above commands on DSL-AC68U in order to be sure you have it.. I tested on DSL-AX82U.

gnuton@DSL-AX82U-FE18:/tmp/home/root# modprobe ip_gre gnuton@DSL-AX82U-FE18:/tmp/home/root# lsmod | grep ip_gre ip_gre 8592 0

Hey I think the problem was these modules are not available by default build. Also they closed GRE tunnels too :)) So can you guide me for ipip tunnel? I'd really appreciate it

Also here is the result of the commands showing I dont have the module by default:

admin@DSL-AC68U:/tmp/home/root# modprobe ip_gre
modprobe: module ip_gre not found in modules.dep
admin@DSL-AC68U:/tmp/home/root# lsmod | grep ip_gre
no response

Here are my active modules if that helps admin@DSL-AC68U:/tmp/home/root# lsmod
