I have setup a PPTP VPN on my Watchguard x550 with appropriate user and policies. I have tested this connection with Windows 10 client setup and can access my office subnet resources. My goal is to connect an SIP phone (no built in VPN) to my PBX.
I purchased a Linksys e1200 v2 with DDWRT (Build 19519) which I attached to my Google Fiber network box. I have tried a few different scenarios, but I am unsure if the PPTP should be configured via the WAN, or Services-VPN CLient setup. I have tried both but do not seem to get access to my office network in either fashion.
My office subnet is 192.168.18.* The PPTP VPN is set to offer 192.168.118.* for DHCP Clients.
Google Fiber box at home is 192.168.1.1 DDWRT router has an IP of 192.168.2.1
Currently I have Services-VPN Client setuP
Server IP=office IP address
remote Subnet= 192.168.118.0
PPTP Username=username PPTP password=password
Any guidance is appreciated.
