Can not ping/connect to our ESA from remote network
I just joined a small company and I am familiarizing with the Ironport ESA appliance (C100V).
I can't figure out why can't our branch office (LAN2LAN) access to the ESA like we do in main office ?
I went through all our network settings (router, switches, acl, nat, routes ...) everything is fine : branch office can communicate with every hosts in the same LAN than the ESA except the esa himself.
Tried to create a new LAN on the main office router to see if it could ping the ESA and it could not (again, ACL etc. are fine)
So naturally I concluded it was a software setting that I can't seem to find neither on ESA web interface or through SSH commands... Is there some sort of firewall on the asyncos or any other rule ?
=> In Sys administration > network access > User Access: I have Allow Any Connection
=> I successfully ping branch office LAN from the ESA (with SSH)
