Hi,

Need to find out how to set up multiple static external IPs on an ADSL modem eg. speedtouch 330 (USB ADSL modem). I've set up a single static IP router (on Debian) before but can't seem to find information on how to manage setting up a block of static IPs and hope that someone here can help. I don't know if it's possible to use the speedtouch for this purpose.

To explain further, my ultimate goal is to have 1 external static IP for my use, another for the my business, another for a bandwidth capped wireless network in my building, another for the test webserver etc. I want to keep the traffic seperated for security and I have other sites I want to connect to externally, which will help with my firewall/iptables configuration on both sides.

Would anyone be able to point me in the right direction?
Will it be a matter of correctly configuring PPPD and maybe using aliases or bridging with the multiple NICs in my router box?
Also any suggestions how to manage the routing would be very useful.

And before anyone suggests it, I also have an ADSL modem router but I'd prefer to use a linux solution.

Thanks in advance
Adam

If you want the debian router to have all the static IPs (or more than one) you can use interface aliases:

Thanks Matir for the suggestion.

I assume that you meant that my ppp connection will have aliases eg. ppp:0, ppp:1 etc rather than eth0:0, eth0:1? Or have I misunderstood what I should be doing with my NIC?
I would expect the modem to grab the IPs and not for me to have to manually configure them? I won't be able to check until Tuesday when the ADSL service is activated.

Also if I wanted to restrict ppp:0 traffic to eth0 and ppp:1 to eth1, would that be solely a routing issue or would I need iptables rules as well to be on the safe side?

Thanks,

By default, any given interface will only grab ONE IP. You'll need to tell it about the others. It should predominantly be a routing issue, yes.
