Description

We have some Synology NAS's that perform backups and due to bandwidth constraints we have these NAT out through a 2nd ISP.

I have a manual NAT rule for this. The NAS's sit on a routed network 90.x.x.x supplied by ISP. This network has zero NAT.

But I wanted to have the NAS's go out via ISP, which I have achieved using policy routing and outgoing NAT.

Under 26.03.1 this works perfectly, but with 26.07 this fails.

I have done a packet capture and can confirm that no packets arrive out of the ISP WAN. If I do a packet capture of ISP, I can see the outgoing packets with no NAT applied, which sadly do not reach the intended destination due to the peer's firewall.
