Hello Community,
I'm trying to setup a VPN connection between XG125w (SFOS 18.0.4 MR-4) and Ubuntu 20.04 box. With no luck. Current configuration works fine on Windows 10 system.
For testing, I've created a fresh Ubuntu installation (the only thing I've done was sudo apt-get update && sudo apt-get install network-manager-l2tpl network-manager-l2tp-gnome).
After connection VPN I have unusual entry in my routing table:
$ ip r
default dev ppp0 proto static scope link metric 50
default via 10.0.2.2 dev enp0s3 proto dhcp metric 100
10.0.2.0/24 dev enp0s3 proto kernel scope link src 10.0.2.15 metric 100
10.0.2.2 dev enp0s3 proto static scope link metric 100
89.x.y.z dev ppp0 proto kernel scope link src 172.21.7.100 metric 50
89.x.y.z via 10.0.2.2 dev enp0s3 proto static metric 100
169.254.0.0/16 dev enp0s3 scope link metric 1000
Everything works fine, when I remove this entry:
sudo ip r d 89.x.y.z dev ppp0
I'm lost a bit. It looks like my XG pushed wrong local IP:
$ tail -f /var/log/syslog | grep -i ppp
[...]

Maybe someone in the community hit this problem an has some advice?
