What ports must be opened?

Sat Apr 30, 2011 1:37 pm

What I want:

Hotspot conection with only this protocols as client: web, dhcp, dnsclient, htpps, live messenger, imap, pop3 and smtp... and those protocols as server: ssh and web...

So... what i need to open is:

Open all outgoing packets with destiny port: 80(http), 25 (smtp), 443 (https), 53(dns), 67(dhcp), 110 (pop3),143 (imap),
993 (simap), 465 (secure smtp), 1863 (msn messanger)... block rest of packets

Open all incoming packets with destiny port: 80, 22 and 8291 (microtik winbox)

Is ok??? I forgot some port???

Thanks

ROS has normally all ports open unless you closed them.
Apart from that, your question doesn't make a lot of sense. "protocols as clients" What do you mean?

Type of data flowing over router is determended by protocol (icmp, udp, tcp, pop3) and port numbers.
For instance, surfing the internet with a browser is tcp protocol and usually (Internet standard) port 80.

.
Dhcp protocol for example... can be used as server (dhcp server) and client (to obtain ip adress), dns the same (server and client), pop3 the same really most of protocols can be used as clients or server....


P.D: I am pkisistemas, my first account was banned because i proposed the use of other brand (to avoid the use of 3 routers in cascade)

I think your are mixing up things. The dhcp protocol, like dns and pop3 is just one protocol. But to transport any date you need at least two parties. A server and a client. In pop3 it is the client that ask by means of the pop3 protocol the server to send the mailbox over.
In dhcp it is the client that requests, the server answers and send the data etc... but all done with one and the same protocol.
