Can't access internal LAN devices after L2TP VPN connection

gaborbiro · September 2019

Dear Zyxel Team!

My device: USG60W with V4.33 firmware.

I created L2TP VPN connection with "Quick setup" option (created user etc.)
I successfully connected to box with my macOS Mojave (with builtin L2TP/Ipsec client).

My problem is: I cant access the internal network devices only if I mark macOS "Send all traffic via VPN" checkbox.

I do not want send all traffic trough USG. I only want to use VPN to connect USG's internal network and leave all other traffic on local macOS internet connection as well.

My VPN address range is different then USG's internal network subnet (this is the rule of zyxel).

Could you help me, how can i do this?

Dear Jasailafan, thanks for your answer! I'm searching a solution that I can set up on my VPN device. Other VPN vendors system can do this I hope Zyxel has solution too.

Hi @gaborbiro,

You also can use SecuExtender (ssl vpn) to establish VPN, you can set up split tunnel on USG.

No need to add routing entry on client.
