Problems with some HTTPS Websites / Intel® PRO/1000 PT Dual Port Server Adapter

[mwagner]

Hi,

I have remarked problems after upgrading pfsense from 2.1.3 to 2.2. I couldn’t open correctly some websites on some interfaces for example:
https://www.mozilla.org/
https://de.yahoo.com/
…………..
On Firefox, only the top of the website was showing. The rest was white. Iexplorer didn’t show anything.

Other sites where working:
https://www.google.de

I have pfsense running on a DELL Power EDGE T20 (Pentium G3220, 4GB RAM ECC) with additional two RJ45 Ports on an Intel PRO/1000 PT Dual Port Server Adapter.

WAN and LAN are on VLAN on different ports of the Dual Port Server Adapter. I have an additional OPT1 on the internal mainboard RJ45.

I had only problems to open the websites on the LAN. To open the same websites on the OPT1 worked well. I have resolved this problem for the moment by switching the LAN network from the Dual Port Server Adapter to a VLAN on the internal mainboard RJ45. WAN is still on the Dual Port Server Adapter.

So logically the problems is related to the Intel PRO/1000 PT Dual Port Server Adapter.

I have already checked a troubleshooting the the pfsense website without change: https://doc.pfsense.org/index.php/Unable_to_Access_Some_Websites

Has anyone an advice what I can do or check or something?

I can not imagine your problem being related to the dual intel adapter itself.
Are your running a proxy? Any customization in the loader.conf at all?

Maybe it is a upgrade issue when upgrading from a lower version of pfsense to the current 2.2 release.

[mwagner]

There is no proxy on the system and I haven't customized the loader.conf.

When I switch back LAN to the Dual Port Server Adapter, the problem returns.

I've upgraded from 2.1.5 with squid3-dev proxy installed, to 2.2 with squid3.4 
I'm not having trouble with https sites.
I use an intel PCI-express dual card.

em0: <intel(r) 1000="" pro="" network="" connection="" 7.4.2=""> port 0xd020-0xd03f mem 0xdf5a0000-0xdf5bffff,0xdf580000-0xdf59ffff irq 16 at device 0.0 on pci1

I also have all off-loading enabled, but I disabled the flow control.

Are you using the DNS forwarder (dnsmasq) or DNS resolver (Unbound)?
I use unbound, also as a package under 2.1.5

You mentioned the top part of the site loads in Firefox, then stops?
Have you cleared the Firefox cache?

Heper's link mentioned a reply asking for info using pciconf.
Here is my pci-express "pciconf -lv"
