ballyboley: "I can ping the slingbox with no issues and access any other IPs across the subnets, however the sling product seems to be adamant it wants to be setup with port forwarding"
I'm having a similar issue... I think. It looks like others have too: https://supportforums.cisco.com/thread/2066112
I can ping the Slingbox while on the same subnet, but it won't respond to a ping across a router; other devices on the same subnet the Slingbox is on respond to the ping just fine across the router... so this i know this isn't a router or firewall issue.
- Ping 172.16.2.254 from 172.16.2.100 = OK
- Ping 172.16.2.254 from 172.16.1.100 = NOT OK
The Slingbox is obviously capable of routing over a private subnet hop and internet (through 172.16.2.1 to 172.16.1.1 to the ISP), given remote viewing works... but I'm not sure why I can't ping the darn thing from the 172.16.1.0/24 network segment when other devices on the 172.16.2.0/24 subnet respond.
I just want to view my Slingbox from a device on another routed private subnet, without using VPN or NAT or Port Forwarding or Bridging. Has anyone else been able to get their Slingbox to work in this seemingly simple manner?
