Re: Trend Micro me bloquea la VPN no se como andara tu nivel de inglés, pero te pego esto, sinó intenta traducirlo o te lo traduzco...
*VPN isn't so much a physical port..such as an ethernet port...but a virtual port. It usually runs on an ethernet port...often the same port as the standard network runs on..but sometimes on a unique NIC also that's dedicated for RRAS.
Also there's what port it runs on...as with TCP/IP...there are over 65,000 different ports. Different applications run on different ports...for example, http/web on port 80, Quake 3 on 27,960, PcAnywhere on 5631 and 5632, etc etc.
PPTP VPN runs on port 1723, IPSec VPN runs on port 500.
How are they configured? Depends on "what" is answering the VPN call. Think of VPN as being not too different from dial up back in the dial up days. Someone placed a call...the remote VPN client/user..and something answers this call...the VPN Server.
With Windows servers...it's still just RRAS that answers this call...basically the same service that answered dial up calls 10 years ago when we used to dial into the office.
More common these days in the business networking world...are appliances that handle the VPN stuff..instead of having your server do it. Right now I'm onsite at an architect firm...they have a branch here where I'm at..one in another state..and shortly..another one opening up on the other coast..in California.
I have VPN routers at both sites..which handle the client VPN connections to the office, and handle VPN tunnels between the two locations..so both networks will talk to each other..basically one big wide area network.
What's nice about VPNs..is it opens up lots of network resources..to remote users..in a secure manner. Instead of opening up tons of different ports to make these services available.* |
