I have a client with multiple sites. At one site they have a security system panel and we have a rule that allows the security company to come in and manage it and that site works fine. At another site we have the same setup but they can't get in. The rule is roughly the same except for the endpoint IP being different of course. I can see traffic on a packet capture for the internet port. Nothing LAN. What can I be missing.
Rule is Internet2 -> Port 2001 -> 10.10.12.252 -> 2001
What else could I be missing?
Thanks in advance
