Hardware Version: V4
Firmware Version: 4.0.4 Build 20200313 Rel.41831

I've been using these for VPN use for years between sites - zero issues.

 

created a new need last year for users to remote into a network, set up different users, and in their settings, assigned an IP address their conneciton should use.  also created a VPN IP Pool, but originally I created a pool that was outside the range of the assigned IPs.  Just noticed today that the assigned IPs weren't being used - users were getting one from the VPN IP pool.

 

I adjusted the VPN IP pool to encompass the assigned IPs, and now the users are getting IPs closer to their assigned IPs, but not their assigned IP.  if I disconnect and reconnect a user, they get a different (next higher) IP from the pool.

 

the User configurition requires assigning them to a VPN IP pool, so i'm wondering if that's overriding their assigned IP.

okay, so maybe I'm not understanding what L2TP is supposed to do.

 

on the router, my VPN account on the router is assigned <subnet>.3 for a Local IP Address. 

 

when connected via my PC using that account, the VPN connection on my Win10 machine shows <subnet>.5, but I can ping the <subnet>.3 IP address.

 

and when I look at the Tunnel List under the VPN settings on the router while connected, it shows a tunnel using my account with that <subnet>.3 IP address.

 

so it appears that the "on network" end of the Tunnel get the "Local" IP address, while the VPN IP Pool is what is used to assign to the remote end of the Tunnel.

 

Is it supposed to use 2 IP addresses on the remote network to create the tunnel?  if so, then the VPN IP Pool probably should not overlap the assigned IP range, correct?

Hi @jnewman67 

Thanks for posting in our business forum.

VPN Pool IP is the IP for the VPN interface.

The local Subnet is the local IP when you connect to the VPN server.

You need a structured lesson on the L2TP VPN. This is how it works.

 

VPN IP Pool should not be overlapped on your model. Not the same thing for the Omada series.
