Relayd / loadbalancer not returning responses to browser.

Hi,

I've configured a slightly unusual SLB configuration where both the virtual IP and the destination host IPs are
on the WAN interface. The /var/etc/relayd.conf file looks fine and I can see from the packet traces that the inbound
packets [SYN] are going to the destination hosts, and the return packet [SYN/ACK] is getting back to the pfsense box, I can't
see the packet going back out to the client.

Any suggestions? I presume relayd is expected to be working with 2.0-RC1 at the moment.

The specific build is …

2.0-RC1 (amd64)
built on Thu Apr 7 04:03:17 EDT 2011
on a Dual-Core AMD Opteron(tm) Processor 1210

Cheers,
Mark

hmm, just misreading some packet traces in the end. I mistook the monitoring probes for browsers requests and failed to spot that the web servers were not sending responses back via the load balancer, but direct to the browser via the main gateway for the subnet.
