Standard VPN for client with same DHCP Scope at home as the DHCP Scope on SonicWall TZ370.

rcolving

I have a client that needs to use the Sonicwall VPN to access here work computer from Home. Her home has a DHCP scope of 192.168.1.x, The SonicWall at work is providing DHCP scope of 192.168.1.x. So when she connects to the VPN she is not given a new IP but she cannot access anything in the work network. Others can connect to the VPN and connect to internal devices. So I'm guessing it has to do with her home IP being in the same range as the work IP range. Any suggestions on how to remedy this would be appreciated.

@rcolving , I think you have two options.

1. Remote user changing her home subnet to a different one, not overlapping with SonicWall subnets.
2. Change the SSLVPN IP Pool and then use NAT over VPN to be able to access 192.168.1.0/24 subnet behind the firewall.

How can I configure SSL VPN/NetExtender for clients with overlapping subnet?
