So did my due diligence and reviewed previous posts but did not find any previous discussion on this topic. I did read https://community.cisco.com/t5/firewalls/asa-5505-to-5506-replacement-using-the-5506-with-bridged/td-p/3075889 which was helpful.
So I've got the new BVI config I'm using now in the hopes of simulating switchports on the 5506 like we used to have on the 5505. PAT is working fine... everybody is getting out on to the Internet.
PROBLEM: The VOIP PBX vendor wants access to the inside PBX (port-forward TCP 35300 -> 443). Below is my config...
object network INSIDE_PANASONIC_PBX
host 192.168.x.200
object service INSIDE_TCP_443
service tcp source eq https
object service OUTSIDE_TCP_35300
service tcp source eq 35300
nat (inside_2,ISP1) source static INSIDE_PANASONIC_PBX interface service INSIDE_TCP_443 OUTSIDE_TCP_35300
nat (inside_3,ISP1) source static INSIDE_PANASONIC_PBX interface service INSIDE_TCP_443 OUTSIDE_TCP_35300
access-list OUTSIDE_ACCESS_IN extended permit tcp any object INSIDE_PANASONIC_PBX eq https
This config seems to be failing. I can telnet directly to PBX on inside IP and Port and works fine so I know it's not the PBX.
If I enable a PCAP on the WAN interface, I see traffic reaching the Firewall.
What do I seem to be doing wrong?
