Summary:
 
Symptoms:

Link light is green on SSG's s1/1 port, but the 'link' and 'protocol' are displayed as down in the 'get int s1/1'  command output.
When the command 'unset interface s1/1 encap ppp'  is run, then the 'link' and 'protocol' come up.
Therefore, PPP won't start negotiating on the s1/1 (WAN interface).

Solution:

Make sure you create a PPP profile, specify encap PPP, and bind the PPP profile to the interface s1/1.

Here's an example of configuring PPP on a single WAN interface:

set ppp profile test static-ip          (create a PPP profile)
set interface s1/1 encap ppp
set interface s1/1 ip 10.0.0.10/24
set interface s1/1 ppp profile test      (binds PPP profile to interface and then starts to negotiate)
