OK - so heres me from one of my live internet [as in colo - no dmz, no nat or anything] web servers
AAA.BBB.CCC.200 - my personal server in DMZ [behind pfsense - public IP routed - no natting - routed in via cisco sdsl router - then next fixed route to pfsense box on WAN1 ]
( AAA.BBB.CCC.200 has a gateway (DMZ1 on pfsense) at AAA.BBB.CCC.193 and a mask of 255.255.255.224 - so in range AAA.BBB.CCC.192 -> AAA.BBB.CCC.223 [ a /27 ] )
AAA.BBB.CCC.228 - a company server, on standard public IP in a data center
( AAA.BBB.CCC.228 has a gateway at AAA.BBB.CCC.225 and a mask of 255.255.255.240 - so in range AAA.BBB.CCC.224 -> AAA.BBB.CCC.239 [ a /28 ] )
DDD.EEE.FF.219 - the public IP of the adsl connected to wan3 on my pfsense box
From AAA.BBB.CCC.228 :
I fired off a 'telnet AAA.BBB.CCC.200 80'
captured with 'tcpdump -n' [ diag_packet_capture.php doesn't want to show any capture at the mo]
10:19:37.476767 IP AAA.BBB.CCC.228.49940 > AAA.BBB.CCC.200.80: S 2457225471:2457225471(0) win 5840 <mss 1460,sackok,timestamp="" 1076751111[|tcp]="">10:19:37.479894 IP DDD.EEE.FF.219.53622 > AAA.BBB.CCC.228.49940: S 712187932:712187932(0) ack 2457225472 win 5792 <mss 1460,sackok,timestamp="" 318338740[|tcp]="">10:19:37.479904 IP AAA.BBB.CCC.228.49940 > DDD.EEE.FF.219.53622: R 2457225472:2457225472(0) win 0
And again - From AAA.BBB.CCC.228 :
I fired off a 'telnet AAA.BBB.CCC.200 25'
captured with 'tcpdump -n' [ diag_packet_capture.php doesn't want to show any capture at the mo]
09:53:35.427471 IP AAA.BBB.CCC.228.49843 > AAA.BBB.CCC.200.25: S 2411757476:2411757476(0) win 5840 <mss 1460,sackok,timestamp="" 1076360598[|tcp]="">09:53:35.499524 IP DDD.EEE.FF.219.64428 > AAA.BBB.CCC.228.49843: S 2037136731:2037136731(0) ack 2411757477 win 5792 <mss 1460,sackok,timestamp="" 318182522[|tcp]="">09:53:35.499536 IP AAA.BBB.CCC.228.49843 > DDD.EEE.FF.219.64428: R 2411757477:2411757477(0) win 0
From any other machine i have tested from thge telnet request connects
[ I think what makes this a special case is that AAA.BBB.CCC.228 is a server we connect to (almost constantly) from our LAN, via WAN3]
I have included the network setups as these ranges are neighbours - which throws up the possibility of me doing something wrong in the basic mask setup etc
As far as I can see,
AAA.BBB.CCC.228 connects to AAA.BBB.CCC.200 [ comes into pfsense on wan1 and goes to AAA.BBB.CCC.200 out of dmz1 ]
AAA.BBB.CCC.200 replies to AAA.BBB.CCC.228 [ comes into pfsense on dmz1 and exits pfsense on wan3 [ why? ] getting natted on the adsl router attached to wan3 ]
so AAA.BBB.CCC.228 doesn't see it as an ack from AAA.BBB.CCC.200
I cant understand why the return path is through wan3 not wan1
Am I right in thinking that the firewall rule allowing the inbound connection should route the reply back out the way it came in ??
I am therefore presuming that this is taken care of by the rules on wan1 and the rules on dmz1 dont come in to it ??
I am at a bit of a loss :
I still think that there is a possibility that a (routing/firewall) rule matching a.b.c.d:m -> e.f.g.h:n maybe catching a.b.c.d:n -> e.f.g.h:m
[ transposing the ports - as if the check is are do the ips match && do the ports match, rather than does the ip/port combo match ]
however I imagine that this would cause more problems and would have been noticed : but then that is the point of BETA - so maybe thats the issue
The only other thing that occurs is maybe i should be aliasing AAA.BBB.CCC.192 ( the network address for teh DMZ if you will ) onto WAN1 ??
[ as it stands it just has 10.0.13.2 with the sdsl router on 10.0.13.1]
Any thought would be appriciated,
Sorry for the mammoth post
TIA
