Title: ADSL + EFW Post by: bartek on Sunday 06 June 2010, 03:21:27 am 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. Bartek Title: Re: ADSL + EFW Post by: bartek on Tuesday 08 June 2010, 08:56:32 am 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. |
