Openvpn sometimes not working with different ISP
-
Hi,
I am using PfSense 2.4.5-RELEASE (amd64) built on Tue Mar 24 15:25:50 EDT 2020 FreeBSD 11.3-STABLE, but I am constantly facing issues with some of our clients who are not with the same ISP. But if I check the OpenVPN logs I can't find any relevant info, I strongly believe my ISP is blocking this with a certain threshold. I had configured OpenVPN with DynDNS since I don't have any static IP, but everything works normally if I change the IP on my WAN interface.If the users are with the same service provider there are no issues, but if it's different ISP- those users are still connected but there would be serious throttling after a few hours.
So as a workaround I need to reset the WAN interface to get a new IP for my WAN and it will work normal for all clients irrespective of ISP. Can someone suggest some permanent solution for this?
Regards

SreyasHave to add one more point, I have multiple site to site VPN this issue will affect those locations too - which are not from the same provider.

Since you've provided very little info and my crystal ball is busted, it's hard to know what the issue is.
Try using nmap to port scan the destination. You can install it in pfSense, as well as on computers running Linux, Windows, etc.. You can also try configuring OpenVPN to use http, instead of the default udp port 1194.

HI JKnott, could you please elaborate "try configuring OpenVPN to use Http, instead of the default UDP port 1194." please, it would be a great help. Since I am struggling with this issue

On the server configuration page, you select the protocol and local port. You'll then have to run client export again.
