I have the issue with my PPTP VPN. When I restart my modem (after which it gets a new WAN IP from my ISP) or when my modem gets a new IP from my ISP every morning, the remote gateway cannot connect to the PPTP VPN server with the new IP.

 

ER605 Router   ---   Modem (Dynamic Global IP)   ----------               Internet                 ----------   ER605 Router (no global IP)

PPTP Server                                                                                                                                       PPTP Client

                                 IP Changes                                               IP of hostname updates                   PPTp Client cannot connect to PPTP Server

                                 After reboot or

                                 at 5 o'clock

                                 in the morning

Hi @vedat 

Thanks for posting in our business forum.

It seems that you have to reconnect the client ER605 or reboot every day to reconnect.

This is common stuff and I have seen this behavior on the Wireguard.

First, it does not reconnect after the disconnection because the DNS cache may still tell the remote server to the old IP address.

Second, during the connection it does not detect the remote server IP if it has changed. So, reconnecting would fix it.
