i have 2 esxi 5.1 hosts to to physically different sites with a site to site vpn set up. i can use my vsphere client at home to remote into both hosts with no issues. i can also get successful ping requests from both sides of the s2s vpn, as well as local name resolution. when i attempt to connect to esxi2 from a vm in esxi1 it comes up with a connection error saying it cant connect for unknown reasons. theres nothing in the security profiles blocking anything and i can get to both of them with the vsphere client from home just not from either side of the s2s vpn.
