NAT with Pfsense 2.0Beta4
-
To resume :
Livebox v2
|
| 192.168.1.13 pfSense
–-------DMZ---------------box ---------------WAN (192.168.1.13)
|--- LAN (192.168.2.1)/24
|---- OPT1 (10.0.0.254)/8PORT 30001 and 40000 are forward in my livebox to WAN IP (192.168.1.13) (but I think it's not necessary because pfsense is on DMZ)
I want to forward incoming connection from internet on port 30001 and 40000 on WAN IP (pfsense) to my OPT1 adress: 10.0.0.254
to then port forward to your OPT1 subnet
I try do do this but it's seems not work (probably I make a mistake)Firewall: NAT: Port Forward
WAN UDP * 30001 WAN address 30001 10.0.0.254 30001WAN UDP * 40000 WAN address 40000 10.0.0.254 40000
Firewall: Rules (WAN)
UDP * 30001 10.0.0.254 30001 * none NATUDP * 40000 10.0.0.254 40000 * none NAT

Are firewall rules applied BEFORE port forwarding or AFTER?
Your configuration appears to assume firewall rules apply AFTER port forwarding. I suggest you check the firewall logs. Maybe firewall rules apply before port forwarding.
-
It's a linked rules on NAT side, pfSense create WAN rules alone.
-
-
Any others ideas ?
I make a tcpdump and the udp packet from Internet seems
to go correctly to my opt1 interface but a always can't connect. -
I have the same issue. I have NATing an RDP port through (port 3389).
When I log a 'pass' firewall rule it shows a success however the connection is not made. It is almost like the routing of the reply packets is not working properly.
My outbound firewall rules are allowing everything currently so I think that the firewall is not the issue.

It's very strange, If I put my server on my modem and put the sames rules in their firewall as above, the connection is possible.
The problem comes for sure from pfSense box, but where that is the question.With pfSense box, I make a tcpdump on my wan and server networks cards.
When I initiat a connection, I see the outgoing packet on UDP 30001 :)
The reply from internet comes also on UDP 30001 and goes to my server IP but connection is not possible ??? ???I don't want to switch to monowall or similar firewalls. I trying to resolve this problem since 3 weeks and finally decided
to ask for helps on this forum.I am sure, a lot "supers" users of pfSense could be resolve our problem.

i can confirm something is not right about multi wan NAT
opt1.modem.ip=192.168.202.1 [modem dmz set to 192.168.202.254]
opt1.interface.ip=192.168.202.254i setup this NAT rule: OPT1 TCP/UDP * * OPT1 address 26001 192.168.0.11 26001
utorrent is on 26001.
went to http://www.yougetsignal.com/tools/open-ports/ to do a port test. says port is closed.
hooked up a test pc and attached modem directly to pc. loaded up utorrent. did port test. says port is open.

I'm seeing the same thing on releases since late October. NAT is working fine on my default gateway, but not on any of the OPT interfaces. So Multi-WAN NAT seems a bit busted at present.

This was fixed yesterday. Try todays snapshot.

Hey there,
I'm running :
2.0-BETA4 (i386)
built on Wed Nov 3 02:54:06 EDT 2010
FreeBSD 8.1-RELEASE-p1… and can confirm that my NAT issues related to this issue appear to have been resolved.
Also, the rule I have on each WAN interface allowing SSH access on a non-standard port (not NAT - just a straight forward PASS rule) is also now working.

Working for me too. Thanks a lot Scott!

I'm having an issue with NAT, not sure if it is the same one as the people here. I am running the latest snapshot:
2.0-BETA4 (i386)
built on Thu Nov 4 01:22:43 EDT 2010
FreeBSD 8.1-RELEASE-p1I've got one WAN interface and 3 LAN interfaces. I set up two NAT rules with Pass as the option. One for SIP (UDP 5060) and one for RTP (UDP 10000 - 20000). One issue is that when I do a packet capture on my WAN interface, I can see RTP packets in the range 10000-20000 come in, but when I do another capture on the LAN interface, I don't see them forwarded to my host. I am also having intermittent issues with the SIP port not always registering. Haven't dug too deep on this one, but I suspect that not all packets are getting forwarded to my host.
-
I don't fully get.. does sound similar to mine…
(public initiates) [modem] -> [opt1] -> [lan] all ok!
[lan] (packet received and responses fine) -> [opt1] (!! never received outgoing packet from lan.) -> [modem] -
Hi,
On my side with 2.0-BETA4 (i386) built on Wed Nov 3 02:54:06 EDT 2010 Can connect now but not every time.
Since this update it work better than previous version but not every time ???Always OK if I use only modem without pfSense.
This night I have instaled monowall to check if it working or not and make few test, now I can connect to my server.
Something is broken in pfSense. I test the NAT and port forward and it's not working on my side (with v 1.23 and latest v2)All work great with monowall if I put the same rules
I hope this problem will be resolved in future releases (I like pfSense)
Cheers

Can anybody confirm these issues or if I'm doing something wrong? I really wanna stay on pfsense and not move to anything else….
i need NAT on opt1 :(
