There may be a simple answer to this, but it sure is baffling me.
We just had a new DSL circuit installed here at work. Our ISDN is still active
and that is what all the clients are currently still hooked up to. The Potato
server I have set up is currently serving ftp services via the LAN. The ISDN
router simply forwards all ftp packets to the server.
There is a second NIC in the server which has been dormant waiting for the new
DSL circuit. The DSL router is configured in bridging mode because the server
will be the firewall/router via ipchains. (It will also be an IMAP server using
Here is the oddity: I ifconfig'd the second NIC, connected it to the new router
(bridge) and was able to download just fine. The problem is that the proftpd
stopped accepting ftp connections. As soon as I did an ifdown on the second
NIC, ftp connections work fine. ifup the second NIC, ftp connections stop
working, just like that.
Is proftpd concerned about who is local or something like that when I ifup the
2nd NIC? Incidentally, I don't want to just give out the new IP address for
people to download from via ftp, I want all of our customers to use the
ftp.*.com address. And I don't want to have our ISP update the DNS yet as I'm
going out of town soon for 3 weeks and I want to change as little as possible
until I get back.
TIA for any help. :) :)
