Systems, methods, and apparatus are herein disclosed for enabling direct communication between two IRC clients without the use of an IRC server once the connection is established. In one instance this can involve a gateway electing to not mangle or not perform NAT on a private IP address of a sending client as a DCC request is passed to the IRC server. In another instance this can involve a gateway mangling or performing NAT on a sender public IP address of a DCC request after it has been passed to the IRC server and returned to the gateway. The clients can be SoftAP clients. The gateway can determine when to mangle and when not to mangle IP addresses using a database that include identifiers of IRC clients on a subnet along with respective IRC servers for those IRC clients.

Direct client-to-client internet relay chat for softap clients

In one aspect, mobile access point devices may provide client devices access to an internet service provider. The mobile access point may communicate with the internet service provider via a cellular connection or a Wi-Fi connection. As the Wi-Fi connection may cause data service access failures due to, for example, firewalls, protocol limitations, or application layer gateways, allowing the mobile access point device to dynamically determine which mode of communication will reach the internet service provider can ensure more efficient service provisioning to the client devices. Packet filters may be maintained at the mobile access point device which identify which connections should be established via cellular and which should be established via Wi-Fi.

Mobile access point connection switching

Methods, devices, non-transitory processor-readable storage media for mapping different local area network (LAN) connections to different data subscriptions of a software-enabled access point (softAP) computing device. A method executed by a softAP computing device processor may include storing a mapping that associates each in a plurality of LAN connections for the LAN established by the softAP computing device with one of a plurality of wide area network (WAN) connections, connecting a client device to the LAN via one of the plurality of LAN connections, routing data traffic received from the client device to one of the plurality of WAN connections based on the stored mapping, and routing data traffic received via one of the plurality of WAN connections to the client device based on the stored mapping. The softAP computing device may also perform re-routing of data traffic based on whether WAN connections are out-of-service or have bandwidth availability.

Providing simultaneous data calls for client devices on a plurality of subscriptions of a multi-SIM computing device configured with software-enabled access point functionality

Methods, devices, systems, and non-transitory process-readable storage media of the various embodiments enable a software-enabled access point mobile computing device to delegate prefixes to already connected local area network (LAN) client devices upon establishment or re-establishment of a data connection. The various embodiments may enable a mobile computing device configured to operate as a mobile router (i.e., a softAP mobile computing device) to support prefix delegation by providing unique IPv6 prefixes to connected LAN client devices.

Technique to delegate prefixes to Wi-Fi clients connected to mobile access point routers

This disclosure describes systems, methods, and apparatus for using a NATTYPE module in a Linux kernel to carry out Full Cone NAT and address-restricted cone NAT while offloading NAT functionality to a hardware accelerator. The NATTYPE module can be configured to create a mapping between conntrack entries and NATTYPE entries and a conntrack module can be configured to update a NATTYPE entry when a conntrack entry is updated and the conntrack entry includes a mapping to a NATTYPE entry. Alternatively, a hardware accelerator controller can be configured to refresh conntrack entries as well as NATTYPE entries.
