Can't seem to figure out L2TP VPN connection for MacOS 10.15.7

I have an EdgeRouter 4 v2.09 HF6 setup to have a L2TP vpn connection for my daughter to connect to the home network from school. I just can’t make heads nor tails of why this won’t work.

Well, effectively it is working. the macbook air (intel) does make a VPN connection to the Edgerouter. If I look inside the users/remote tab it shows the remote user VPN connection and shows blocks of data being sent. It is just she cannot seem to see or connect or even ping any of the local devices even by direct ip address. I don’t think it is anything wrong with my edgerouter setup as I can connect perfectly fine from my Windows Laptop to the home from remote locations. I can connect perfectly fine from my iPhone using iOS16 when I am out and about. So I take it the VPN is working fine. It is just this laptop that is having an issue.

I am writing here to just double check that anyone can think of anything that would be causing an issue that I wouldn’t have thought about. I can post a scrubbed config from the edgerouter if that would help. I don’t know if anyone out there using an edgerouter with a remote Mac that vpn connects to them.

I’m with you in thinking it’s a client side issue.

Is it “sending all traffic”?

Could be a network “issue” at her school — they might be blocking VPN traffic. Do you know if it connects or not over a different network?

Humm… yes that could be a possibility. I am heading up to see her in a few weeks. I will bring my laptop that I know works fine and connect to her Wi-Fi and see if my laptop works. That will be a good diagnostic to rule out the network. Might see if she can slice out some time from her busy “school life” and take the laptop to an Internet cafe and try connecting from there. It’s less of a definitive test but might get a result faster. Thanks. That gives me some starting point of something to look at.
