Model: ER605 (TL-R605)

Firmware Version:

Hi,

I have set up a site to site office scenario where a branch office connects to a home office using ER605s. I am using Omada controller and the branch office connects successfully to the home office and i can ping the ER605's from both ends. From the home office i can also ping the PC that the branch office controller software is running on, but no other devices. I cannot ping any devices on the head office. I've watched the youtube videos and have tried to set this up many times, but always the same results. Any help would be appreciated. 

 

From the log on the home office

 

4 2023-11-15 15:43:44 IPsec NOTICE [osg:40-ED-00-6E-BC-EE]: Set up IPsec connection successfully. (Peers=x.x.167.85<->x.x.58.109)

6 2023-11-15 15:43:43 IPsec NOTICE WAN: Phase 1 of IKE negotiation succeeded. (Peers=x.x.167.85<->x.x.58.109)

Hi @hoffmanjp 

Thanks for posting in our business forum.

Question, is the 192.168.0.1 or 192.168.1.1 pingable? I mean you ping the remote subnet gateway. e.g. when your PC is in 192.168.0.1/24, ping the 192.168.1.1 which is the VPN remote gateway.

Regardless of computers' IPs, I need to know if the gateway is pingable or not. This should be pingable by default.

Mostly, the computer is not pingable due to the firewall issues. I just need to make sure your VPN tunnel is through. The firewall issue would be the MS problem. Usually, use the Private Network would allow access.

Duh, works great now. Didn't even dawn on me that it was the stupid firewall.

 

Thank you Thank you Thank you!
