Private traffic over two firewalls not working
-
Hi,
I've create the following setup
192.168.1.1 | LAN –---- Transparent FW1 ------ WAN | ----- L2 vlan ---- | WAN ------ Transparent FW2 ------ LAN | 192.168.1.2
I want to be able to communicate between the two private lans which is not working now. When I use Public ip's in the lan segments then it works.
I disabled Block private networks and Block bogon networks.
When I open a http session from 192.168.1.1 to 192.168.1.2 I see the request arriving on the FW2 in the packet capture and I see the response back, but with a bad cksum 0! That reply does not arrive back on FW1.
What could be the cause of BAD CHECKSUMS (pfsense bug?) (I imported the dump in WireShark and it still was bad) Could this be the reason that this setup is not working?
Last but not least, how to fix this ?

If the checksums are done in hardware, software tools will often think they aren't right even though they are correct, but were handled at the hardware level.
If you suspect it's the hardware checksums, there is a checkbox under the Advanced options to turn them off. It wasn't clear from your message if you had already tried this step.

Yup, that was it. Thx m8. It's now working smooth. :)
