My new small white one, please answer, online data for seven and eight fall superior unit to pull the root private network, the network is connected, but some port spell, what reason be

CodePudding user response:

Firewall blocked some port

CodePudding user response:

A firewall or blocked on the server

CodePudding user response:

You're also seven and eight down this line is not the Internet? What port can't? Is your ping not to go out, or outside ping doesn't come in?

CodePudding user response:

Private network network online unit, my side port of the upper unit, my side didn't open the firewall and shielding, whether to do inside the routing strategy

CodePudding user response:

Is generally firewall blocking you, it is also possible that vlan corresponding, or the net off by default

CodePudding user response:

Is a firewall blocking, have nothing to do with whether the shuttle

CodePudding user response:

Ping the IP first, see if I can make it, no problem can lead to indicate that the network strategy, Telnet IP port again, can see through, can not pass, but the other port is not open, or the port was taken, or blocked

CodePudding user response:

How vlan division?

CodePudding user response:

Firewall Settings should be blocked by those who can't use the port, in order to improve the system security

CodePudding user response:

Previously met some port operators restriction, can confirm,

online unit private network, Intranet, port of the upper unit on my side, my side didn't open the firewall and shielding, whether or not to do in routing strategy

The ping program is to use the icmp protocol, it is to look at the address I can reach, such as cannot be used to check the port, the port can use professional scanning tools, can simply use Telnet XXXXX port, and we can't open port, to see your superior, not all of the ports are open, general will only open for you some necessary port, all other ports block, prevent you sabotage,

CodePudding user response:

Direct superior to find feasible port, general guess not to come out

CodePudding user response:

Buy a thread gauge, to rule out the first line there is a problem, if the line is no problem in the routing set shielding, general early recovery factory set up good, individual check the port configuration

CodePudding user response:

Cable if you have any questions, whether the firewall block, the other cables plugged into the switch if you have any questions in the port

CodePudding user response:

Firewall off line not line, also do not reset the port IP and VLAN

CodePudding user response:

Between different operators may have restricted some port, there are different between the operators of docking is not very good sometimes prone to network docking, I have come across, you are there any restrictions under rule out a firewall, access the full opening, unrestricted, give it a try,

CodePudding user response:

Power envelope, need to apply for

CodePudding user response:

Look at the firewalls' policies

CodePudding user response:

See what port, general blockade is 80, but you are a special line, should not be sealed,

CodePudding user response:

Put through icmp port ban ping, firewall

CodePudding user response:

Could they turn off the port, which port you will ask the carriers
