Proxy Server ( HTTP & Proxy No)

Hi All

We have added a proxy server (with IP & Port No). We tested two pages with Tcode-SE38--RSWF_TEST_HTTP--Entering URL-Execute & with Tcode-OAC0. The test was successful.

My question is

a) Does it mean that SAP can access only these two pages OR any page?

b) Does it mean that people/users can use access SAP system (say quality or production) from the port?

Regards
