ADSL + EFW
«

Hello there forum,
I am new to EFW but not so new to firewalls and proxy's.
I am having trouble understanding how to configure my modem (Thomson TG508) and my RED interface.
Right now I am testing efw inside a VirtualBox (VB) on a debian machine.
Debian has no assigned IP's just the efw inside VB.
I have 3 network cards. The modem is in bridged mode.
eth0 is my internal network GREEN
eth1 is my RED with 1 adsl provider (dynamic ip)
eth2 will be a second adsl provider after I managed the first one.
efw managed to create my ppp0 and logs in to my provider and gets a public ip
efw created as well a br0 with my internal IP 10.2.0.X
I have for now disabled proxy and am using just the firewall.
I did create a Port forwarding from my RED uplink on a high port to a internal machine (10.2.0.X) on port 3389 for RDP.
But I cant access the machine from outside.
I created as well on Incoming routed traffic a rule to allow port 22 for ssh connections, but this as well fails.
I did a tcpdump and all I see just arp requests between the modem and efw.
now I am new to this dsl modem stuff and am wondering how to configure it the best way.
do I have to or not to, configure my eth1 with dhcp from the modem?
how does efw actually the trafficking?
I tried to navigate, but the only page I get to open is google, everything else is just waiting for response. So I figure the problem is somewhere between my modem and efw.
I really appreciate your help.

Ok in the end my problem was everthying else
it was the MTU!! I had to change it to 1412!
for whom ends up with the same problem:
you need to edit /etc/ppp/peers/dsl-provider
and on the line where mtu is you put in your flavor.
