Archer AX73(US/CA/TW) V1 1.2.0 Build 20211222 rel.74632

 

Issue Description/Phenomenon:

After upgrading the router firmware to 1.2.0 Build 20211222 rel.74632, the devices (e.g. computers and phones) behind AX73 can no longer connect to the PPTP VPN Server. It used to work fine with the previous firmware. The typical topology is shown in the following picture.

 

When these devices connect directly to the ISP modem bypass AX73 or use mobile data, they can connect to the PPTP VPN Server without an issue.

 

Available Solutions:

1. Update and install the latest official firmware on the AX73.

2. If the clients still fail to connect to the PPTP VPN Server, please check and enable the PPTP Passthrough (Advanced > Security > ALG page) as follows:

 

Let the community know if there is still an issue.

  @Kevin_Z 

Was having great difficult connecting to company VPN, could get it through cell phone hotspot, but not home AX-73.  This beta fixed the problem, now PPTP vpn is working great!

 

Thanks for your help.
