This is the first post on WAN connection setups. I’ll be using and SRX110 was it has a built in ADSL/VDSL port. I’ll be connecting to a dynamic IP ADSL service based in the UK. The service is a BT type configuration. The SRX has been loaded with the factory default config prior to this exercise.
Step 1: Disable the pt interface
We are using the ‘at’ interface for the ADSL so the ‘dual personality’ port needs setting up.
root# deactivate interfaces pt-1/0/0
Step 2: Set up the ‘at’ interface
root# set interfaces at-1/0/0 encapsulation atm-pvc root# set interfaces at-1/0/0 atm-options vpi 0 root# set interfaces at-1/0/0 dsl-options operating-mode auto root# set interfaces at-1/0/0 unit 0 encapsulation atm-ppp-vc-mux root# set interfaces at-1/0/0 unit 0 vci 0.38 root# set interfaces at-1/0/0 unit 0 ppp-options chap default-chap-secret "your_password" root# set interfaces at-1/0/0 unit 0 ppp-options chap local-name "your_username" root# set interfaces at-1/0/0 unit 0 ppp-options chap passive root# set interfaces at-1/0/0 unit 0 family inet negotiate-address
Step 3: Correct the interfaces in the zones
We need to swap the pt interface for the at interface in the default security setup.
root# delete security zones security-zone untrust interfaces pt-1/0/0.0 root# set security zones security-zone untrust interfaces at-1/0/0.0
Step 4: Add the default route
root# set routing-options static route 0.0.0.0/0 next-hop at-1/0/0.0
