It seems they used an access rule to allow incoming connections from external networks!
I duplicated their scenerio and indeed access rules for incoming connections did work. Can someone help me understand the difference betweek the two? What if publish was used instead of the access rule?
Thanks, Edgardo (feeling like such a newbie right now )
If there is a ROUTE relationship between the source and destination Networks, you can create either an Access Rule or a Publishing Rule.
If there is a NAT relationship between the source and destination Network, then you can create Access Rules from the NATed Network to the destination Network, and Publishing Rules from the non-NATed Network to the NATed Network. For example, if you have a NAT relationship between the Default Internal Network and the default External Network, then you create Access rules from Internal to External, and Publishing Rules from External to Internal.
