    Hi,

    for SBA, Edge server on the primary site is still the AV call flow route for remote users. So are there channels of comm's / port open between SBA subnet & Edge internal DMZ subnet / IP address ?

    Hi,

    Sorry for the delay, you're alright, we have some sba where we didn't open ports in the firewall. This error has dissapeared now.

    Thanks
