Today marks an exciting release for IAPS Security Services, Ltd. We are releasing our first AT&T Wireless Dynamic Residential VPN Service.
Based on a pool of 250 AT&T Wireless ip addresses, and the availability of users getting a different ip address every time they connect to the vpn service, this will provide users with more than enough ip addresses to suit virtually all their needs.
Whether you do online surveys, data mining, Supreme New York shopping, or any other activity that requires a lot fo residential ip addresses, this is a service you can’t afford to miss.
Benefits of this service:
A pool of 250 AT&T Wireless Dynamic Residential IP Addresses.
You get a new ip address every time you connect to the vpn server.
*Dedicated IP Address Available Upon Request, otherwise system remains dynamic*
PPTP (Point-to-Point Tunneling Protocol)
L2TP (Layer 2 Tunneling Protocol)
SSTP (Secure Socket Tunneling Protocol)
PPTP tunnel is instantiated by communication to the peer on TCP port 1723. This TCP connection is then used to initiate and manage a GRE tunnel to the same peer. The PPTP GRE packet format is non standard, including a new acknowledgement number field replacing the typical routing field in the GRE header. However, as in a normal GRE connection, those modified GRE packets are directly encapsulated into IP packets, and seen as IP protocol number 47. The GRE tunnel is used to carry encapsulated PPP packets, allowing the tunnelling of any protocols that can be carried within PPP.
The two endpoints of an L2TP tunnel are called the LAC (L2TP Access Concentrator) and the LNS (L2TP Network Server). The L2TP LNS waits for new tunnels. Once a tunnel is established, the network traffic between the peers is bidirectional. To be useful for networking, higher-level protocols are then run through the L2TP tunnel. To facilitate this, an L2TP session (or ‘call’) is established within the tunnel for each higher-level protocol such as PPP. Either the LAC or LNS may initiate sessions. The traffic for each session is isolated by L2TP, so it is possible to set up multiple virtual networks across a single tunnel.
Secure Socket Tunneling Protocol (SSTP) is a form of virtual private network (VPN) tunnel that provides a mechanism to transport PPP traffic through an SSL/TLS channel. SSL/TLS provides transport-level security with key negotiation, encryption and traffic integrity checking. The use of SSL/TLS over TCP port 443 allows SSTP to pass through virtually all firewalls and proxy servers.
