How does nat work with incoming UDP packets from unknown?
My understanding of NAT is that UDP packets going out from the client to a specific endpoint will result in a temporary entry into the NAT table mapping the source port to the destination endpoint. (Is this right?)
How does behind NAT to behind NAT connection work?
The basic idea is simple, you tell each endpoint the ports to use, and they start sending udp packets. The NAT’ing devices will set up a traversal rule when they see the first outgoing packet, and then the next attempt from the other end will match this traversal rule. You need a mediator server, so the clients can tell where they are.
Is the interface IP address part of the Nat pool?
Do not configure the interface IP address as part of the IP address NAT pool. By default, support for the Session Initiation Protocol (SIP) is enabled on port 5060. Therefore, NAT-enabled devices interpret all packets on this port as SIP call messages.
Which is the IP address for a NAT gateway?
IPAddress — NAT Gateway IP specifies the IPv4 or IPv6 address to use as the NAT gateway IP. The generic form will be a.b.c.1 (e.g. 172.16.0.1). While the final position doesn’t have to be .1, it usually is (based on prefix length) A common gateway IP is 192.168.0.1
Among the new features and UI is an option to make a connection “Shared to other computers”. This is basically a dead-simple NAT (Network Address Translation), or Internet connection sharing, built right in to NetworkManager. To enable this, you must follow three steps:
What is the version of network manager in Ubuntu?
If I open existing connection (eth0) and change method from Manual to Shared to other computers then all my settings disappear. NetworkManager version 0.7, shipped with Ubuntu 8.10 and later, contains a redesigned user interface for managing network connections.
