Configuring Transparent Mode

danswartz

but can it ping the WAN gateway IP? I am reading conflicting statements about this.

globalmcs

I can ping the WAN IP 24.XXX.XXX.50, but not the WAN Gateway IP 24.XXX.XXX.49 from the server in OPT1

I have a total of 5 IPs from the ISP, one for the WAN and four for the server in the OPT1

danswartz

if you login to the pfsense, can you ping the WAN gateway IP?

globalmcs

I haven't tried it, I'll do so tonight - I'm not there right now and dont have remote access yet.

globalmcs

I changed the OPT rule to one
Proto Source Port Destination Port Gateway Schedule
* * * * * *

I was able to ping the WAN Gateway from the pfSense console

Ping output:

PING 24.xxx.xxx.49 (24.xxx.xxx.49) from 24.xxx.xxx.50: 56 data bytes
64 bytes from 24.xxx.xxx.49: icmp_seq=0 ttl=64 time=1.537 ms
64 bytes from 24.xxx.xxx.49: icmp_seq=1 ttl=64 time=1.262 ms
64 bytes from 24.xxx.xxx.49: icmp_seq=2 ttl=64 time=2.456 ms

–- 24.xxx.xxx.49 ping statistics ---
3 packets transmitted, 3 packets received, 0.0% packet loss
round-trip min/avg/max/stddev = 1.262/1.752/2.456/0.511 ms

I ran the packet capture on the WAN interface and pinged 24.xxx.xxx.49 from the server in OPT1 and here is what I got

12 2.041353 00:50:56:94:1a:b4 Broadcast ARP Who has 24.XXX.XXX.49? Tell 24.XXX.XXX.51
13 2.782611 24.XXX.XXX.50 24.XXX.XXX.49 ICMP Echo (ping) request
14 2.783796 24.XXX.XXX.49 24.XXX.XXX.50 ICMP Echo (ping) reply
21 3.783133 24.XXX.XXX.50 24.XXX.XXX.49 ICMP Echo (ping) request
22 3.784322 24.XXX.XXX.49 24.XXX.XXX.50 ICMP Echo (ping) reply
23 4.784588 24.XXX.XXX.50 24.XXX.XXX.49 ICMP Echo (ping) request

So the server broadcast who has 24.XXX.XXX.49, the ping starts from the WAN IP and the Gateway replies back to the WAN IP instead of the Server IP

Aha. It sounds like it is doing NAT for some reason. If you go to firewall => NAT => Outbound, what do you see?

globalmcs

The option "Automatic outbound NAT rule generation (IPsec passthrough)" is selected.

danswartz

aha, click to AON (manual) and delete the rule that then appears.

globalmcs

I did it and lost internet connectivity from the LAN and the OTP1 still the same.
I selected the "Automatic outbound NAT rule generation (IPsec passthrough)" back.

danswartz

sorry, my bad. re-enable manual AON and tell me what rule you see.

globalmcs

Its ok, I appreciate you trying to help me.
Here is the only rule when manual AON is Enabled

Interface Source Source Port Destination Destination Port NAT Address NAT Port Static Port Description
WAN 192.168.1.1/24 * * * * * NO Auto created rule for LAN

danswartz

okay, that is correct. can you post contents of /tmp/rules.debug?

globalmcs

I hope you dont mind but I emailed it to you, didn't want to post it.

globalmcs

Hey Dan, I just wanted to let you know that with version "2.0-BETA3" the Transparent Mode (bridge) is working. I notice one issue on the server in OPT1, if I restart it can't get out to the internet 'till I "repair" the network connection.

By repair I mean, in Windows going to Network Connections right clicking on the connection and selecting the option to repair.

Thanks for all your help

danswartz

glad it is working. if this server has a static IP what you are describing is odd. be interesting to run a packet trace on the OPT1 interface after booting the server and then doing the repair.

globalmcs

Hi, sorry I didn't get back to you sooner, I was not able to reproduce the error to run a packet capture - I'll make sure to run capture it if it ever happens again.

Thank you again for all your help!
