Step5. Go to Configuration > Network > Routing > Policy Route, add a policy route
rule to route traffic from local subnets to all branch offices to IPSec VPN tunnel
to_HQ.
Incoming interface: LAN1
Source: LAN1_Subnet (192.168.5.0/24)
Destination: range_br(192.168.1.0~192.168.5.255)
Next Hop: VPN tunnel to_HQ
Since the SIP clients in branch offices register to the SIP server through IPSec VPN
tunnels, the VoIP traffic doesn‟t go over NAT, we can leave SIP ALG disabled on all
the USG ZyWALL.
After all the settings on both the HQ and branch offices are done, dial up the tunnels.
All the VoIP clients can register to the SIP server through the VPN tunnels, and they
call make VoIP calls to each other through VPN tunnels.
