What are all protocol that doesn't like multiple WAN??

[thenewguy1979]

Can someone give me a list of all protocal or port ranges that doesn't like Multi-WAN?

So Far I have HTTPS, POP3, and SSH. I have set them up on my firewall rules but I want to update this list to include any potential incompatible port ranges I may encounter in the future.

Thanks

PPTP VPN. You need to send PPTP (port 1723) and GRE out over the same interface or the connection cannot be established and if it is, will eventually time out and drop when GRE and PPTP are sent out over different WAN interfaces.
