I have two Realtek RTL8111G card on my mainboard, one is defined as WAN and other is LAN, using the box as router (pfsense).
After around 1hour the routing freeze if I disable he WAN and than enable again it start working.

Currenly I`m running on the Binary 1.95

Is there other also experience issue or know what I can do ?

I you need more information please let me know, have dragged out som information from the box, IP adress has just replace with XXX.XXX.XXX.

I have tried to get some help from pfsense forum, but haven`t been able to fix the issue, and since the pfsense is running on Freebsd in the buttom,
I was hoping it was other Freebsd user with the same network card here ???

Thank you for using time on me....

Realtek cards are cheap crap. Spend some money and buy Intel cards. Even the cheapest Intel cards are way better.

FreeBSD have notoriously bad support for Realtek cards.

I researched this issue some time ago, it seams that for some reason FreeBSD network stack hangs up under load with Realtek cards.

It seams that there is no current effort for debug and fix this, so only solution will be to use expansion card, Broadcon and Intel works well.
Go to pf-sense site for detailed compatibility list.

Like SirDice said; save your money and buy an Intel NIC.
Notice that quality motherboards use Intel interfaces and bargain brands use Realtek.
You get what you pay for.

Realtek drivers now in the ports.
So procedure is as follow.
1. pkg install realtek-re-kmod
2. Edit /boot/loader.conf and add:
