for about half a year i have my own firewall pc running with devil-linux and in the beginning all went fine.
but then, i started having problems without having changed any of the settings done by configuring.
I never got away with the problem and now my 1mbit cable is slower then a 56k because of collisions.
the firewall works with 2 nic's
eth0 : i-net comes in, recieves IP from DHCP from ISP
eth1 : this is the router of the firewall, and passes out the internal IP's to the rest of machines.
now the odd thing is that the card having collisions is eth0 and that sucks tbh.
eht0 = realtek NIC
eht1 = 3com NIC
I have also tried changing the nics from PCI-slots which hasn't helped me much.
hereby comes another odd but verry annoying problem, IRQ problems.
since I'm a fan of the rtl chipset on NIC's I have 3 realtek nic's but the problem is that when I insert 2 RTL nic's in the firewall he has a problems with IRQ.
it seems to me that the computer gives the 2 pci's NIC's the same IRQ which isn't correct cause with sharing IRQ's my firewall software doesn' tknow which one is eth1 or eht0 and so the firewall doesn't work.
my guestion is,
1) how do I get rid of the collisions?
2) how do I get my computer to give a non-sharing IRQ to my 2nd RTL nic
Next odd thing is that apparently no matter how much collisions I get, when only 2 computers are connected the speed doesn't suffer under it.
but from the moment a third pc gets his IP from the firewall, speed goes down the drain with it.
