  • 1.  BT Infinity and PPPoE Configuration

    Hi,

     

    First time using this community as I have only recently been thrown into the world of Juniper. I bought an SRX210B to use for lab work at home and am trying to get it working with my BT Infinity circuit. The physical link appears up and so does the PPPoE session (from what I can work out) but the logical link is down. Can anyone provide assistance?

    Hi there,

     

    Check out my post, it may help you out.

    You need to do vlan tagging on the pt-1/0/0 interface, are you doing that?

     

    Cheers

    Oh it look like you are using the provided modem rather than the PIM.

    Try using chap instead of pap

    Thanks for that, I ended up trying that a few days ago and hey presto! All working now, although I have had to play around with the MTU/MSS config to get it sound. I'm using an MTU of 1492 on the pp0.0 interface and have set the internet options MSS to 1452, does that sound accurate to you?

    Glad I could help.

     

    Yeah  it sure does.

    I had to do exactly the same. Most websites worked, but some did not. As soon as I set the MSS, everything worked perfectly.

     

    You mean like this?

       

    flow {
            tcp-mss {
                all-tcp {
                    mss 1300;
                }
            }
        }

     

    Looks like I went a bit lower than you but same thing really.

    I didn't need to set the MTU on the actual pp0 interface, this covered it.

     

    Cheers

    Hi

     

    I am trying to configure a SRX100H to a BT Infinity circuit - would you be a s good as to share your completed config?

     

    I am struggling to configure the fe-0/0/0 interface as the underlying-interface.

     

    Many thanks.
