Wonderful Info About How To Find Out Your Mtu

Example (just searching for mtu):

How to find out your mtu. Here, it is easy to put the mtu value as you do need to trial and error. This may vary depending on a router’s brand and type. The best value for mtu is that value just before your packets get fragmented.

Here we found that packet is fragmenting when its size is at 1473 bytes which means the maximum possible size here is 1472 bytes. Just type in the similar value as you. You will simply send out ping requests and progressively lower.

But this is not the mtu value, to find it. As a workaround you can use the ping command at the operating. In our case mtu value = mss + ip header + icmp header.

That being said, let’s move on to finding the optimum mtu value. Navigate through your router’s configuration settings until you find the mtu field. The simplest way to establish the optimum mtu is by using the ping command and iterating the mtu setting.

Basically, you have to click on ‘wan’ to find the ‘mtu’ settings page. To find out if your packets are getting fragmented, we use a ping command from the command prompt. Mtu = mss + tcp/ip header.

Now let's add 28 bytes reserved for the data header (20 bytes for the ip header and 8 bytes for the icmp request. Finding the correct mtu to find the correct mtu for your configuration you must run a simple dos ping test. You will simply send out ping requests and progressively lower your packet size.
