AsusWRT router can resolve company restricted URL. Openwrt can not

[lbnp]

My company requires accessing company resources via VPN. On the same computer:

• An Asus RT-AC86u router is able to access company resources on Gitlab
• A GL-iNet MT-1300 Beryl router is not

In both cases:

• The routers have their own .ovpn files and act as an openvpn client. I can not test connecting to the company resources with this router vpn configuration turned off.
• The routers are connected by WAN (the ISP router) with an ethernet cable
• The routers are connected to the test computer by ethernet cable (one at a time during testing)
• Both routers appear able to connect to the company VPN itself
• Both routers are able to connect to other, unrestricted resources (internet) just fine.

Anyone have an idea with the Beryl might have trouble? The difference I would guess is the software, Asus-WRT vs OpenWRT. The later has a much simpler admin area but I just don't know the settings to test out to get it to work.

Usually the OpenVPN client has a log, which could provide a clue.

DId you configure the OpenWrt firewall for the VPN? AsusWRT does it automatically, OpenWrt you need to do it as a separate setup.
