I need IP Passthrough for my server but I also need to access it from the local network… So I bought an extra network card and thought I could connect that to the internal network and the main NIC straight to the modem for that IP Passthrough. Unfortunately, when I configure and connect the second NIC the main NIC shuts completely off after a while.
Only removing second NIC from /etc/network/interfaces and restarting networking service helps to bring the main NIC back up.
What am I doing wrong here?
Server is running Debian testing
(Linux strangelove 4.7.0-1-amd64 #1 SMP Debian 4.7.8-1 (2016-10-19) x86_64 GNU/Linux)
Someone said I should update to testing which I did, problem still occuring.
That someone also said its the drivers. I’m saying its more of a PEBKAC or something in the configs.
NICs are (according to lspci)
02:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller (rev 06)
03:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller (rev 02)
Not sure which is which…
The motherboard is a Gigabyte GA-F2A85X-UP4
EDIT: managed to make it work
