static nat vs port forwarding

You redirect the port number “80” in destination-port statement to the port 8080 in “mapped-port” statement.

So with static NAT the Internet can initiate traffic to the inside host and there would be no need for port forwarding in this case. How-To Videos

static route=manually configured IP route to a particular subnet port forwarding=forwards tcp or udp incoming connections to a machine connected to the router doing the forwarding… We were able to do this only by destination nat feature but it was a bit clunky in comparison to this feature.

For example to match on UDP port 10001 on interface eth8 and internal LAN host 192.168.1.50, use: sudo tcpdump -n -i eth8 udp port 10001 and host 192.168.1.50. Can anyone tell me what the difference is? Auto-suggest helps you quickly narrow down your search results by suggesting possible matches as you type.

Configuration is pretty straight forward.

Message 1 of 2 (12,366 Views) I have 5 static IP Addresses, and I would like to run multiple webservers on my connection. I recently had my router replaced like last month, and I am using the following: MI424WR-GEN2 with firmware 20.9.0 and its fully updated. Starting with junos 11.4R5 (If I remember correctly), you can also forward ports by static nat  configuration.

The only difference I see is that with the port forward, I

I was using the MI424WR Rev D prior to it going bad, and I could host multiple web servers just fine with each public IP statically routed to the static LAN IP on my private network, however, after this switch I am only able to run 1 webserver on my 20 Megabit Synchornous FiOS Business Class Connection.

I have tried power cycling the modem, power cycling my computers and to no avail I cannot get the other servers to be contactable via outside my LAN.This has been fixed in the most recent router firmware. You can modify these tcpdump commands listed above to match the ones used by your Port Forwarding or Destination NAT rule. So if you are doing dynamic NAT or PAT and you have a server which should be accessible from the Internet then you would need to do port forwarding.

So i am confuse in the sense between Dynamic NAT + Port forwarding vs PAT static

I have 3 servers that are able to run Apache via Linux and Windows ala WAMP.

NAT allows many devices on an “inside” private network to share the connection to external networks and the internet through a single device.

Thanks.Thank you for updating the post.

You redirect the port numberWhen you are dealing with NAT in SRX, always keep in mind the order of NAT operations i.e If you want to have the SET commands of this configuration simply go to [edit security nat] config level of your device and then paste it as instructed below and press Worked for more than 10 years as a Network/Support Engineer and also interested in Python, Linux, Security and SD-WAN, currently living in the Netherlands and works as a Network Support Engineer.
