Configure 2nd NIC on Tjener?
Dear List,
our Tjener is a FSC TX150 and has a well performiner on board NIC (1GB RJ45)
which presently runs 100Mbit FD. LTSP is running on a separte machine.
The concept of skolelinux is to run Tjener with only one NIC (10.0.2.2) that
is connected to the "barebone" linking internet router, ltsp servers, work
stations.
The reason why we mounted a 2nd NIC (eth1) into our Tjener was, that
- our backbone switch has a Fibre MBit uplink
- some remote buildings connect to a Fibre MBit Switch
- we owned a spare Fibre Gigabit NIC anyway.
Now, we think about _activating_ eth1. Basically there are three options:
(1) replace eth0 by eth1
(2) use eth0 for internet connection, eth1 for intranet (Tjener = Firewall)
(3) use eth0 for incoming, eth1 for outgoing traffic.
Option 1 involves editing /etc/network/interfaces to map eth1 to eth0.
Option 2 would restrict outgoing traffic passing Tjener. I suppose, it was
mainly squid settings to change.
Option 3 sounds most interesting as most of Tjener's traffic is outbound. I
suspect however that most requests _do_ care if replies come from another IP
than the request was sent to.
Don't worry, I am quite patient before doing any changes - but discussing
pro`s and con`s is something we should start here.
Thank you
Regards
Ralf
