Topic: PPP0A and more

[cjensen]

Hi,

Here's my senario:

Connection to DSL through an ISP which offers ONLY ppp0a.  Wireless lan in place previous to DSL.

SME Server (latest release 6.0.1) installed and intended as a filter (squidguard).

I have not found a viable solution to connect the SME server-gateway as normal with the ppp0a, using ethernet.  
So my first question is whether anyone has succeeded at this.

Second, is there a configuration which I could use to proxy the clients in the lan through the SME and thus filter internet through it?

Anyway, the default for the DSL setup of course is to single windoz machine and they 'don't support linux'

I have been using PPPoA on SME for years. There are several ways of setting it up.
 
Set up the ADSL router with your username and password. You need to reconfigure the SME server to use static ip for the external ethernet port and set the ip to be in the same subnet as the LAN ip of the ADSL router.
If you have a dynamic ip address then you will need to use a third party Dynamic ip address program to check your ip via web e.g checkip.dyndns.org:8245.
Personally I use ipcheck.py   http://ipcheck.sourceforge.net/ and use a cron job to call ipcheck.py regularly

The other option is that a lot of new PPPoA ADSL routers have a function called half-bridge mode. This allows you to forward your ip address to the external port on the server via the DHCP server in the router. You will need to re-configure the external port on the server for "Use DHCP (send ethernet address as client identifier)".
This method has the advantage that it disables the NAT firewall on the router and allows you to use the in built dynamic DNS clients on the server.

Thank you for the reply Jon.

I will check out both options.

I find that the DSL 'gateway' as the ISP calls it has no bridge option in those words, but they do have this:

1. NAT can be turned 'off'
2. 'Static Routing' as it is called in the advanced config of the 'gateway' allows you to set,
'Subnet IP', 'Subnet Mask', 'Gateway IP'.  It also states the 'Gateway IP' can be empty fot local subnet.

This 'sounds' like the same as what you mentioned as 'half-bridge' mode.  I am inclined to try these settings on the DSL Gateway.  I am assuming that I would be routing 192.168.0.1 (the IP of the Gateway device) and using DHCP on the external port of the server.  I am not sure of any other changes on the server end.

I will give this a try.

Thank you,
