Debian server: VPN and NIC matters
I have a Debian server which must be placed behind a secured corporate Intranet.
Only way in is via a VPN.
The app deployed on this server needs to "call home" to a remote server via the Internet to check for latest updates, patches, data, licensing info, etc.
There are 2 NICs on this server:
- First one is configured for the Intranet LAN and the app server is listening on this NIC's IP because the app is being served to Intranet users.
- Second NIC is configured to a gateway which has Internet access, and this NIC's interface is disabled by default and is only turned on on demand.
1) How can I bridge the 2 interfaces such that the app is able to access the Internet via the 2nd NIC interface?
2) When I connect to the server through VPN from outside, I can ssh into the server but the moment I do "ifup eth2" I lose the ssh connection. Is there any way (e.g. some config settings maybe?) to allow me to still maintain the ssh connection after the 2nd NIC is up?
