Safe business network

      We offer Corporate Customers the opportunity to receive an individual GPRS access point in order to organize high-security connections for data transmission using GPRS.

      Technical requirements

      Sending information

      The connection between the network and the access point is provided via the internet. Data transmission from the access point to the network takes place using the GRE protocol (IP protocol number 47).


      The data transmitted between the network and the access point is encrypted using the IPSec protocol (IP protocol number 50) using the ESP (Encapsulation Security Payload) mode of the protocol. The automatic exchange of IPSec parameters and keys takes place according to the IKE (ISAKMP/OAKLEY) protocol. Initially, only UDP protocol traffic addressed to port 500 and IPSec protocol traffic are allowed between peer encryption devices. When implementing a technical solution, this condition can be changed as needed.

      Initial IKE parameters

      IKE 1st phase (ISAKMP SA)

      • LMT pre-generated PRESHARED SECRET;

      • cypher 3DES CBC;

      • hash function MD5;

      • MODP group 2 or 5;

      • SA lifetime 4 hours.

      IKE 2nd phase (IPSec SA)

      • ESP mode;

      • cypher 3DES CBC;

      • hash function MD5;

      • PFS not allowed;

      • Aggressive Mode not allowed;

      • SA lifetime 1 hour.

      The above parameters can be changed if such changes are accepted in writing by LMT.

      User authentication

      Authentication information is transmitted using the RADIUS (RFC 2865) protocol. User authentication can take place at LMT or the Corporate Customer by agreement. The Corporate Customer must provide information about the server's IPv4 address and authorization key.

      IP addresses

      IPSec gateway and GRE end-point addresses must be public. All other IP addresses (mobile terminals, RADIUS servers) can be both public and private. If the Corporate Customer uses public IP addresses, they must be from the range of public IP addresses owned by the Customer. The Corporate Customer must specify how large the range of IP addresses of mobile devices will be, as well as the distribution of ranges between LMT GPRS routers. Regardless of where user authentication takes place (at LMT or Corporate Customer), the Corporate Customer determines the type of IP addresses (dynamic or static).
