Hi.

how do i share my private internet connection over the HSMM net? 

to make it "simple" and have all system in one place. I would like to have internet access at my repeater tower. to connect  aprs,echolink and d-star ++ so my idea is to use the HSMM system to wireless send my private internet connection to my repeater QTH

So i have one linksys router at home connected to my ISP router, and i have a connection to my other HSMM linksys router at my repeater location.

they are talking to each other. but can't get the internet connection i need. 

is there a special thing i have to do. to make this work. 

If I understand your configuration correctly it looks like this:

Home router <-cable-> MESH-node-A <-RF-> MESH-node-B <-cables-> Repeater-site-devices

Comments:

1) MESH-node-A needs to check the box in setup to advertise the internet gateway.

2) The Dstar gateway (configured appropriately and plugged into MESH-node-B) will be able to initiate outgoing internet connections, e.g. aprs reporting.

3) Special port forward settings will need to be made on the MESH-node-A (by hand in firewall settings) to enable incoming connections to the Dstar gateway and other repeater site devices, e.g. echolink, Dstar to Dstar linking, etc. You will need to know how to do this or enlist this expertise.
