NAT reflection hacking
Trying to get OpenWrt do NAT the way I want Todays struggle is to get traffic from my main PC to debian-test VM working properly. I think I found the key to the solution in OpenWrt fw4 feature called “NAT reflection”. In the firewall port forwarding rule settings on Advanced tab is a field “Reflection zones” which to kinda do what I want. But it didn’t quite work right because the zone didn’t have the right subnets etc. The simple solution was just add another port forward rule from lan zone with wan IP address, and that seems to have resolved everything. One concern is that if my wan ip changes then does the rule auto-update or is it now fixed on the current wan ip? Naturally I also needed to have static route 89.27.8.195 via 192.168.31.162 dev eth2.301 defined in openwrt-r5s. Still need to figure out way to auto-update that.
