Multiple IP addresses and NAT

$

Hi,

 

I have an issue when using EdgeOS v1.8.

 

I previously had 1.6 installed with multiple IP addresses assigned to an interface (my ISP is providing a /28 and I have all the addresses setup on the interface except for the gateway). On those secondary IP's I have a number of port forwardings to IPs inside the network, which all work properly when using v1.6.

 

When upgrading to v1.8 those forwardings have stopped working and when connecting from the outside i get a connection refused (i can see with tcpdump that the request is going through but seems to be sent to a different port than the specified on the nat rule on the inside service and hence i get a RST and a connection refused). Weird thing is if i do the same using the main (i use main to refer to the first) IP setup on the interface of the ISP, the nat goes through perfectly.

 

Any idea of what is going on? Have there been significant changes on NAT or so over v1.7 or v1.8? Haven't checked if the issue is also there on v1.7

 

Cheers
