Hi all. Although this is my first post I have been using Astaro for many years. I currently have an ASG110/120 unit with V7.5 and its external interface used to be connected to a bonded DSL router which in turn had 3 dsl speedtouch modems hanging of it. Along with this the ISP provided 5 public IP's. The Astaro was provided with one and the others were used for various front facing servers behind the firewall.
The company closed recently and a new buyer has purchased the assets and I have been asked to get IT systems back up and running albeit on a much simpler scale. I will not be going for the bonded dsl solution again and have simply opted for a business broadband deal from BT with a static IP as I plan to have the astaro handling incoming mail again and then passing to my Groupwise server.
I have my broadband live now and have tested it with the standard BT router and all is well so I now come to the point were I want to connect the broadband to the astaro. I still have the speedtouch modems which were used for the bonded router so i thought of just using one of them and connecting it to eth2 and changing the interface type from its current 'ethernet standard' to 'DSL (PPOA / PPTP). It is this part that I am getting confused with as my overall IP knowledge is limited. I am required to enter a modem ip as well as an NIC address and netmask. On reading the admin guide it states the NIC address must be in the same subnet as the modem. If I only have one public static IP from BT, is it possible to carry out this setup or do I need two IP's (one for the modem and one for the astaro?). Another option I presume is to use the current BT Broadband router and disable the firewall on that and somehow configure it to pass traffice to the astaro. I could then keep the interface as 'ethernet standard'??
I presume I could use NAT forwarding in the astaro to forward different types of traffic to different internal IP assigned servers.
Hope that was clear and appreciate any help.
