Hi guys, I have a problem which need your help.
Peplink Balance Mode: BPL-210
Firmware: 6.3.3 build 2526
I’m trying to setup inbound port forwarding for one of my customer’s video conferencing. The setup is as follow:
Peplink — Fortigate firewall — LAN
The firewall has DNAT configured with ISP1 public IP (A.A.A.A) mapped to customer’s internal video conference equipment (184.108.40.206).
The Peplink currently has the following configuration:
- Add A.A.A.A IP as a server.
- Map ISP2 IP (B.B.B.B) to A.A.A.A via inbound port forwarding on all TCP and UDP ports.
VC works fine on both connections. However, once we disconnect ISP1 connection, our customer tried to establish VC using B.B.B.B as destination IP, but the call drops as soon as it is received. Does anyone know what could be the issue? The firewall does not show any deny action so we can assume the traffic is being allowed in.
