hi dear community
need help with following
External router IP 1.1.1.1
camera vlan id=103 network 192.168.103.0/24 with gw 192.168.103.1
corp vlan id=100 network 192.168.100.0/24 with gw 192.168.100.1
inside vlan103 I have camera 192.168.103.2 with service protocol\port=tcp\9999
user 192.168.100.100 should access 192.168.103.2:9999 via external IP (tcp\9999 only)
all traffic between vlan100 and vlan103 - blocked by firewall
If the Camera is on a different subnet from the users attempting to access the camera, hairpin NAT is not required and regular NAT should simply work.
