I had to edit an ACL on an active S2S VPN today because traffic was being denied from a host onsite to a host on the remote site (port 449). After I made the change, we tried to make the connection again, but it was still denied. Do we need to tear down the S2S vpn for the change to the ACL to take effect?
Also, what if we just wait for the connection to rekey itself? Will it work after that?
