Dear Sirs,
How do i circumvent a MITA (man in the middle attack), for the last 6 years, there have been ec2-AWS Host Spider Bots, for lack of better terms, "sitting" on my optical network terminal that intercept the 3-way encrypted handshake, and thus redirect, block, and cause general problems. I have blocked the IPv4 addresses with the Modem T3200M (based on 'Busy-Box'), but to no avail, I've taken the following steps to remedy this: changed DNS servers once a week, leave ONT & modem power unplugged until ready to use, changed account phone number with ISP several times @ $25 a pop, replaced 12 modems, changed ONT 4 times, reinstalled OS a dozen times, changed the network name to a JS Error associated with bots, switched to a 4 year old modem with totally different settings,
asked the ISP to ban the Bots, which triggered a Ddos attack which lasted 12 hours the first time, 8 hours the second.
Additionally, after boot-up, of computer and modem, my homepage is the modem main front page, I log in, and check the NAT table, which has traffic from: Google of Amsterdam Netherlands, Rochester Institute of Technology, and CloudFlare, among many others.
I don't think I caused this by streaming to twitchTV.......

ANY help would be greatly appreciated even for my ISP as well.

Thank you for your love

I got the love for ya, but no solutions.
Sordid reading.
I can, however, believe a streaming service (or its 3rd parties) capable of all this treachery.

the MITA is happening over wan for you? This shouldn't be your problem, this should be taken care of by your ISP. If this is from your home, you can do release/renew on ip from your modem if it lets you or contact your ISP and ask for a new IP on a different block. good luck bud!
