Dear All,

this Router have 2 Interface as following :-

1- the First Interface is connected to MY ISP Router with this IP :-

213.x.x.109 /248.

2- the Second Interface is connected to MY Switch 'UNMANAGED SWITCH ', with this

IP :-

213.255.237.113 / 248.

-----

the People who are behind interface 213.x.x.113 / 248, are 3 Peoples.

as follsoing :-

1- First PC --- have this IP 213.x.x.115 .

2- Second One --- 213.x.x.116

3- third one----213.x.x.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.x.x.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 .

Try this,

add 2 more access-list with your configuration

access-list 103 permit tcp any host 213.255.237.117 eq smtp

access-list 103 permit tcp any host 213.255.237.117 eq pop3
