Sounds like a MTU issue (PMTUD perhaps?). I’m guessing the other side of the VPN was wanting MTU to be 1500 bytes, but due to PPPoE overhead the client won’t ever be able to receive the full 1500 bytes. So it’s sad and won’t work.
We use PPPoE and had one customer that couldn’t get to a random vendors webpage. Turns out the webserver he was connecting to was incorrectly configured and always replied with 1500 byte MTUs even though the sender says “no, I can’t do 1500 bytes!”. Wireshark packet capture told us that. I suspect something similar for your issue. -c > On Feb 26, 2018, at 5:06 PM, Chuck McCown <[email protected]> wrote: > > Had a customer that works from home.
