Hi all - thanks in advance for any help given. I've got a strange outbound routing question. I've got 2 routers, with a series of devices connected behind them, one in New Zealand, one in Australia. Our NZ device is not given a Public WAN address by our ISP, while our Australian device is given 2 (on purpose). We have a finance app that needs to talk to and from the Internet via the second Public IP we are given on our Australian connection. I already have an outbound NAT rule in place so that the finance workstation in Australia NATs out all Internet traffic from the right IP address, but how do I do the same from a new finance workstation in NZ?
I've attached a quick diagram of the network layout for easy reference.
Australia Router #1
WAN IP 1– 130.102.4.19
WAN IP 2 - 130.102.4.20
LAN IP – 192.168.20.1/24
New Zealand Router #2
WAN IP – 10.10.10.10
LAN IP – 192.168.10.1/24
PC #2 in Australia = 192.168.20.45 and outbound NAT's to the 130.102.4.20 WAN IP 2.
PC #2 in NZ = 192.168.10.55 and needs to cross the VPN tunnel and outbound through the same Public IP now.
How do I configure the NZ router to forward all traffic across to Australia, and then have the Australian router NAT the traffic back over the VPN successfully?
Thanks for any help and guidance
Jay
