Single Host Not Connectible (QNAP) - Highly Unusual

[adprom]

Have a weird issue I have done some diagnosis of.

Situation is as follows:
Network 1 behind pfsense connects to network 2 behind a fritzbox. Everything can connect to anything and that works well. Except for one situation. On network 1, there is a QNAP fileserver. It cannot connect to anything on network 2 and vice versa. On network 1, the pfsense is actually a virtual appliance within an vmware esxi host.

This is where it gets odd, after a pfsense reboot, from network 2, you can ping the qnap and 1 ICMP request will work and all others from then on will time out. Same situation if you ping any host on network 2 from the qnap.

Even weirder, ping the pfsense router from the qnap - and that works fine. Run a traceroute to the fritzbox from the qnap and you get the following:

traceroute to 192.168.0.1 (192.168.0.1), 30 hops max, 40 byte packets
1  Fileserver (192.168.1.1)  3007.03 ms !H  3005.7 ms !H  3005.96 ms !H

You get weird response. High response times and doesn't even try for 2nd hop.

From any other host:
Tracing route to 192.168.0.1 over a maximum of 30 hops

1     2 ms     1 ms     1 ms  pfSense.local [192.168.1.254]
 2    36 ms    35 ms    34 ms  192.168.0.1

Before pfsense 2.0.1 this worked fine as well. No issues with interconnect. I have also tried doing a fresh reinstall and same result, so appears to be a bug that has introduced. Also, there is a QNAP on network 2 which I can access from network 1 just fine. I have changed the IP address of the QNAP to see what happens, same thing. Everything else works fine which suggests routing, firewall etc is all fine. Nothing appears in firewall log.

In addition to that on startup you get the following:
:.     02-25-13 21:47:46 - [filter_load]There were error(s) loading the rules: /tmp/rules.debug:61: macro not defined/tmp/rules.debug:61: syntax error/tmp/rules.debug:62: macro not definedpfctl: Syntax error in config file: pf rules not loaded The line in question reads [61]: rdr on $ proto gre from any to any -> 192.168.1.220     .:.

192.168.1.220 is a remote access server which is defined under pptp redirection. So the warning appears like it could be unrelated, but I don't know.

All settings were entered manually. For the fresh install, I deployed the ova template rather than installing myself.

Workaround! Just found due to another post that this is fixed by http://forum.pfsense.org/index.php/topic,57995.0.html

Frustrating to say the least
