Firewall switchover management in telecommunications networks

A method of managing communications through a network gateway, the method comprising:

• receiving, by an internet gateway, a data stream from an external network;
• receiving, by a route server operatively connected to a first firewall and a second firewall, route advertisements from the first firewall, wherein the first firewall and the second firewall are connected by a communication link;
• updating, by the route server, a routing table to direct a data packet of the data stream from the internet gateway to a network router via the first firewall;
• in response to a determination that the first firewall suffers a failure condition:
• beginning to receive, by the route server, the route advertisements from the second firewall, and
• updating, by the route server, the routing table to direct the data packet from the internet gateway to the network router via the second firewall;
• and
• selectively transmitting, by the network router, the data stream to an internal network.

A non-transitory computer-readable medium storing instructions that, when executed by at least one processor of a route server operatively connected to a first firewall and a second firewall, cause the route server to perform operations comprising:

• receiving route advertisements from the first firewall;
• updating a routing table to direct a data packet from an internet gateway to a network router via the first firewall;
• and
• in response to a determination that the first firewall suffers a failure condition:
• beginning to receive the route advertisements from the second firewall, and
• updating the routing table to direct the data packet from the internet gateway to the network router via the second firewall.
