Hi !
I am customer of german provider KAMP, who is offering DSL Flat with 8 static ip for very reasonable price.
this works via ordinary DSL/PPPoE - the way how this is setup may be a little bit exotic and i didn`t really understand in all depth what i was doing when i setup my linux box (acting as router and running virtual machines on), but in the end i got it working and it`s working well for more then two years.
now, the problem is: i want to put an astaro in between (i.e. setup an additional astaro box acting as dial-in-router and firewall etc.) - but - how to do that ? is this possible with astaro ? could someone probably help with this?
basically/essentially, setup is looking like this (i obfuscated my ip-adress):
server has a lan interface which is connected to a switch. that switch is connected to the local lan and to the dsl modem. so eth0 is sharing PPPoE connection with other IP traffic. not the perfect way to do (as you should use a dedicated nic for your dsl modem), but it works without problems.
111.111.111.145 is on eth0, which is default-gw for my local lan, which is 111.111.111.144/29 - so i have left 4 adresses for use, because the first one is the network address, the last one is broadcast and one is for the default-gw. the whole lan is public, i.e. i can reach each ip from the internet.
this are the intefaces:
eth0 Link encap:Ethernet HWaddr 00:0C:76:E8:50:FE
inet addr:111.111.111.145 Bcast:111.111.111.151 Mask:255.255.255.248

mind, that 1.2.3.4 is of no use here - it could be _any_ ip adress because this one isn`t involved in routing.
this is my routing table:
vmhost:/ # route
Destination Gateway Genmask Flags Metric Ref Use Iface
195.62.99.234 0.0.0.0 255.255.255.255 UH 0 0 0 ppp0
111.111.111.144 0.0.0.0 255.255.255.248 U 0 0 0 eth0
0.0.0.0 0.0.0.0 0.0.0.0 U 0 0 0 ppp0
vmhost:/ # ip route
195.62.99.234 dev ppp0 proto kernel scope link src 1.2.3.4
111.111.111.144/29 dev eth0 proto kernel scope link src 111.111.111.145
default dev ppp0 scope link src 111.111.111.145
so, what i`m basically doing is "routing everything onto the ppp interface".
is there some special term for this setup?
it is hard to find examples for this setup on the net, but i assume other providers may use this method, too.
anyway - any help for putting an astaro box "in between" would be very helpful.
