[kwlug-disc] VPN Traffic

[Francisco Dominguez]

Maybe they check the PMTU / MTU and make some assumptions… IPSec + GRE can bring things down to 1420 / 1440

I suspect most other VPN implementations would do the same / similar

They refuse to connect to any page other than their home page if you use a VPN.   I phoned them - got to third(!) level technical support and they told me that they now block all VPN traffic.  The very technical person at RBC said they do this because all scammers and fraud only use VPNs.  I explained to them that I use a VPN for increased security and privacy.  She said she completely understands and she uses VPNs as well, but this was a high level security policy and she didn't see this being changed at all.  I understand their position as well.   Moving money around while hiding your true IP address may indicate something is not quite right.
