Q: Ipad Port 35837 suspicious network access
I reviewed my router logs -- I am getting a huge number of LAN accesses from suspicious IP addresses to my IPAD on Port 35837 (like 1-4 attempts per minute) -- checking the web, these IP addresses are coming from Latin America and Eastern Europe -- two questions:
1. Any idea what is running on this port or how I can check
2. How can I block a specific inbound port on the IPAD
iPad Air, iOS 9.3.4, Apple support is poor

Since you saw this in your router logs, the simplest test is just power off the iPad for awhile and see if the traffic ceases.
If it is just incoming requests to the router and they are being blocked by the router, then there is no issue anyway, and it would indicate nothing inside your intranet is running on that port - some is just sniffing for open ports. There are some reported Windows trojans and root kits that will use ports in the 35-thousand range.
iOS, being a sandboxed operating system, only opens a port at all if it is needed by an iOS service or an App. Otherwise, iOS blocks all ports.
