I have a bit of a strange problem here.
I have two Cisco RVS4000's setup with a VPN between them at two different sites. For testing, I have everything security-related 100% disabled on both little routers. No firewall, no IPS, nothing.
Everything works between the two sides, and I can access everything as if it were sitting right next to me (RDP, FTP, HTTP, ICMP, etc.)... Except 443.
Trying to access anything over https gets network timed out errors. What would be the cause of this?
The VPN settings for both sides are as follows (identical of course):
IKE with Preshared Key
Ph1 : 3DES / SHA1 / Grp 1024bit / Lifetime 28800
Ph2 : 3DES / SHA1 / Perfect Foward Secrecy Enabled / ***PSK*** / Grp 1024bit / Lifetime 3600
