when changing Port no.
- YUP! This is concerned with Security to the n/w
Suppose i configured HTTP port no. on FIREWALL changing its default port no. 80 to something else as 4040...
(1)it will block outer side HTTP request to our n/w
(2) Firewall will translate port no. 80 to 4040 if any request comes from outer side

if the option 1 is applied then it means that we will tell to related outer sider user the port no.4040 if he requests for HTTP

if option no. 2 is concerned then it's useless if it translates in between port no.
then why change if locally port no. if it will response to every outer side HTTP req!!!

Any assistance you can provide would be greatly appreciated :kiss:
