Connection blocking to specific IP address
Within the last week, it appears connecting to a specific IP address (91.189.95.85)has become throttled / blocked / rate limited. I can only make somewhere in the neighborhood of 7open connections before I am temporarily blocked from making any more simultaneous connections. This is not a problem on my home LAN internal network as I have tested this at multiple cox home networks in the same neighborhood with the same results. I have also run the same tests from non-cox networks (including from an AWS machine), and my test is not being blocked there in any capacity. This leads me to believe there is something new on the cox network that is rate-limiting or throttling outbound connections going to a single destination. The test I am running is: xargs -I % -P 5 curl -I "http://ppa.launchpad.net/ondrej/php/ubuntu/pool/main/p/php-imagick/php8.0-imagick_3.4.4+php8.0+3.4.4-7+ubuntu20.04.1+deb.sury.org+1_amd64.deb" < <(printf '%s\n' {1..8}) using {1..7} will complete, whereas {1..8} will hang on the last connection, and eventually time out with: curl: (7) Failed to connect to ppa.launchpad.net port 80: Operation timed out I am unsure where else to go to find a resolution to this problem.Solved1.6KViews0likes1CommentResident to resident traffic block?
My sister is a Cox Internet subscriber as am I, and we both reside within Rancho Santa Margarita. I remotely administer her router or sometimes remote control her machine from mine for troubleshooting. As of a few months ago, this stopped working. If I connect my laptop to my MiFi, I am able to connect to her router and remote session. When I connect my laptop back behind my router, connected to Cox Internet, I cannot. Did Cox setup an internal route to block resident to resident traffic within the same city? As a test, a friend of mine, also on Cox but located in Lake Forest, allowed me access to his router. I can get to his just fine. Why can't customers within the same POP (area) get to one another? Please keep in mind this works perfectly if I am NOT on Cox's ISP. From a Starbucks or from my MiFi, it works perfect. So this is NOT related to any inbound port blocking Cox does.2.3KViews0likes3Comments
