- Route VS NAT: when and why user either of them
An overly simplistic view is NAT is what the WAN interface on a router does, routing is what occurs afterwards on the LAN interfaces This is also what separates a router from a switch - switches route packets, but cannot do NAT, and this is also why a router is always required between a modem and downstream devices –
- Solved: What is faster, routing or NAT? - Cisco Community
The complexity of the NAT appears to be higher but from the viewpoint of the number of operations when rewriting pure L3 headers in a static 1:1 mapping, there may be fewer operations than if routing a packet over a routing table containing tens of thousands of entries
- Dynamic Routing Protocols: OSPF, EIGRP, RIPv2, IS-IS, BGP
The routes advertised are based on the routing protocol configuration Common routing protocols such as OSPF, EIGRP, RIP, IS-IS, BGP, along with static and default routes support IPv4 and IPv6 address space Network devices such as routers and Layer 3 switches support multiple dynamic routing protocols
- Demystifying Destination NAT vs Source NAT with Bidirectional
Static source NAT Bidirectional: This NAT Rule enable traffic to be initiated in both direction, inbound connection initiated by external users on internet to the server using its public IP as the Layer 3 destination IP 13 1 1 10 then the firewall translates it to the serve's private IP 172 16 1 10 and outbound (new) connection initiated by the
- networking - Dynamic vs Static NAT? How to tell which and when one or . . .
Dynamic NAT just means that on the "remote" side of the NAT wall, addresses will be mapped from an assigned pool both static and dynamic mapping do the same thing (forget public and private, its not important to static dynamic) the question is whether you wrote a mapping rule for ever address on the left network, mapping it to a specific
- routing - Use case for “RoutedWithNat” vs “Bridged” vs . . .
The third scenario, routing without NAT, comes in handy when, once again, the LAN is controlled by your routerA (including DHCP, DNS, and routing), but for some reason you want some of your packets not to be routed the traditional way, but thru some other complex scheme: for instance, if you wish to use some kind of proxy that makes it look
- Static and dynamic NAT - Cisco Community
In cases where static dynamic NAT have same local address space (say 10 0 0 0 8) AND When route-maps are used for both static NAT and Dynamic NAT configurations Workaround: Either don't use route-maps with Static configs (see order above) Or put deny statements in route-map of dynamic NAT to explicitly deny static local address The
- Solved: NAT with dynamic routing - Cisco Community
Hello, Is there a way I can track interface status and use this tracking to do NAT for LAN subnet? I have three WAN interfaces and only one of them is going to be active at any given time I would like to NAT my LAN traffic to whichever WAN interface is up at that time of the day How can I acomp
