[SOLVED] Outbound binding to specific WAN IP

[labsy]

Hi,

I've asked this question elsewhere, so hoping maybe I get answer here.

What's the proper method to specify, for example LAN server with IP xy to use outbound masquerade using WAN IP xz? I have multiple WAN IP addresses and I want each local server to use it's own public IP (not all going out via the same IP...especially I want to specify outbound WAN IP for mail server).
I have 17.1.6 and I've tried OUTBOUND NAT using Virtual WAN IP, but no joy.Tried also with floating NAT rule, direction out, use different Wan IP as a gateway...but this does not pass traffic to real Wan gateway, instead traffic is stuck at WAN port.

I know this is one of hte basic functions, but how to approach?
...or is maybe 17.1.x buggy?

It was obviously a bug in FreeBSD kernel, as update to 17.1.8 solved the problem instantly:
