My current setup is the following:
ATT ISP ---- ATT wireless router ---- cisco 890 wireless router
My cisco 890 is for internet and remote VPN access from home to my company, however, I don't have access/priv to modify or look at the running config of the router. I could however, connect to some of the ethernet port of the 890 for non-corporate traffic, which I'm allowed 1 or 2 ports for this access.
So I use the cisco router for corporate access mostly, but use the ATT wireless router for regular home use (for my wife actually).
I'm in the process of acquiring 4 cisco 3560 switches and setting up a server with GNS3 for CCIE R/S studying.
My goal is to set up a secure remote connection from the internet to my home server with GNS3, but not sure where to set up or terminate the connection, that is on the ATT or Cisco router or even on the server.
I've heard it can be done via port forwarding, but not recommended. Instead use SSH or VPN. I'm sure my IP from the ISP is via DHCP, so somehow I need to get it static or find other way to still work even if via dhcp.
Is it better to use SSH and terminate at the server? If so, how would I handle this via the att/cisco routers as intermediary devices?
Or is it better to use VPN? I guess I would need to terminate the VPN at the cisco router, but this assumes my company allows me to modify the config. If so, how could I handle this from the ATT router as an intermediary device?
appreciate the help!
