Re: sin conexión a los puertos 110, 143 desde dentro de la LAN
Matías:
este es el output de lo que me sugeriste:
> nmap -v -O -o /root/escaneo_del_servodor 192.168.0.1
Starting nmap V. 2.54BETA22 ( www.insecure.org/nmap/ )
No tcp,udp, or ICMP scantype specified, assuming vanilla tcp connect()
scan. Use -sP if you really don't want to portscan (and just want to see
what hosts are up).
Host server.financialinvestmentservices.net (192.168.0.1) appears to be up
... good.
Initiating Connect() Scan against server.financialinvestmentservices.net
(192.168.0.1)
Adding TCP port 110 (state open).
Adding TCP port 80 (state open).
Adding TCP port 631 (state open).
Adding TCP port 200 (state open).
Adding TCP port 443 (state open).
Adding TCP port 127 (state open).
Adding TCP port 515 (state open).
Adding TCP port 901 (state open).
Adding TCP port 139 (state open).
Adding TCP port 25 (state open).
Adding TCP port 143 (state open).
Adding TCP port 22 (state open).
Adding TCP port 3306 (state open).
Adding TCP port 3128 (state open).
Adding TCP port 88 (state open).
The Connect() Scan took 0 seconds to scan 1542 ports.
For OSScan assuming that port 22 is open and port 1 is closed and neither
are firewalled
Insufficient responses for TCP sequencing (3), OS detection may be less
accurate

Interesting ports on server.financialinvestmentservices.net (192.168.0.1):
(The 1527 ports scanned but not shown below are in state: closed)
Port State Service
22/tcp open ssh
25/tcp open smtp
80/tcp open http
88/tcp open kerberos-sec
110/tcp open pop-3
127/tcp open locus-con
139/tcp open netbios-ssn
143/tcp open imap2
200/tcp open src
443/tcp open https
515/tcp open printer
631/tcp open cups
901/tcp open samba-swat
3128/tcp open squid-http
3306/tcp open mysql
No exact OS matches for host (If you know what OS is running on it, see
http://www.insecure.org/cgi-bin/nmap-submit.cgi).

Aparentemente está todo bien....
No etiendo qué pasa....

"nmap -v -O -o /root/escaneo_del_servodor_o_lo_que_quieras IP_del_SERVIDOR")
Y podrás echar una mirada más completa de lo que está pasando.
