I am configuring a Cisco 877 router in a test environment. We use a non-standard port for SFTP, 3030. On my inbound ACL I am setting
permit tcp any any eq 3030 but the remote SFTP connection is being refused.
We use a non-standard port for SQL too, and this is set on the same ACL, but works fine. When I do
sh access-list it doesn't show any matches for the SFTP rule at all, unless I attempt a port probe. All other ACL rules work fine.
What am I missing to allow through this connection? I've even tried to set port-map SSH 3030, as this is the protocol used once a connection has been established, to no avail.
