IP :-

213.255.237.113 / 248.

the People who are behind interface 213.255.237.113 / 248, are 3 Peoples.

as follsoing :-

1- First PC --- have this IP 213.255.237.115 .

2- Second One --- 213.255.237.116

3- third one----213.255.237.117.

======================================

untill Now, every thing is Clear.

MY E-mail server is hosted in MY ISP Side, and i am using POP3 Account to access it from any where .

Now, the Third user which have this Real IP Address ( 213.255.237.117 ), reported to me that , he is UNABLE COMPLETELY TO RECEIVE ANY E-MAILS using POP3, but he is able to send " SMTP", and able to browse Internet " HTTP".


the others Users did not reported at all like this Problem at all.

and all of them able to send / receive / browsing .


to make a test over his PC , i shutdown his PC Completely, and i put my LAPTOP instead of him, and with the same IP and i found that the same Problem.


All the IP are real IPs for the 2 interfaces which is F0/0 & F0/1 from MY ISP.

-------------

the Router is have this Access List:-

so where is the Problem ?

could it be from the ISP HIM SELF ? or from my router .

you have not mentioned that which access list is applied on which interface.


also you need to re-build access list 103 as your access list doesn't tell that what exactly you are trying to permit or deny.


It has source network like 172.16.x.x, 213.255 in your ACL which are not assigned to your network. your network has 213.255.252.112/29 but still they are part of ACL.


you need to be sure of what exactly you need to permit/deny traffic coming from inside network 213.255.252.112/29 and then prepare ACL
