UDP packet won't send if it is too small

mx flag

I am in an incredibly odd situation. Basically if I try to send UDP packets smaller than 1445 in size they never end up reaching their destination. I have a pretty ordinary router and a pretty ordinary Macos based computer.

Here is the test that I am running:

On server:

iperf -s -u -p 4445

On my mac:

iperf -c xx.xx.xx.xx -u -p 4445 --len 1445

^ This works perfectly (and also any number higher than 1445)

iperf -c xx.xx.xx.xx -u -p 4445 --len 1444

^ This is completely broken (and also any number lower than 1444)

Does anyone have any ideas why this might be?

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
