OpenVPN access on cruise
-
Howdy, I am having trouble with OpenVPN as deployed by pfSense from cruise WiFi (Norwegian/"Starlink"). I have successfully used this same connection all over the world, from WiFI hotspots and over numerous captive portals. Once in a while, I have to change the port, but otherwise I have never had a problem.
Now I am on a ship and I have the premium "Starlink" package supposed to support VPN, etc. I have a latency of about 150ms. from the coast of Africa to my home pfSense public IP, so not horrible.
My OpenVPN does connect without issue and I am able to ping all IPs on the LAN, however other traffic fails. RDP authenticates and then holds on a black screen for 30-40 seconds, quits. I have even limited my colors and bandwidth.
When I try to connect to the pfSense webpage, I get nothing.Any ideas?
THX,

@unsichtbarre Most probably its an mtu issue. Try lowering it.

@netblues absolutely! 1300 is the magic number. Thanks,

@unsichtbarre There are no magic numbers. There are only either guess-and-checked numbers—or numbers tested up to the maximum functional byte size.

@tinfoilmatt Well, I started counting down from 1472, but got impatient. Started going in 20's. 1300 worked. Shame on the captive portal LAN admins!

@unsichtbarre A binary search would get you to the happy number fairly fast and is easy to impliment.
