About a decade ago I took the CCNA course but not the certification , so I have a good level of knowledge. I do IT support for a non profit and we acquired an SR520. We chose it because we want to set up 3 to 5 VPN's allowing a few folks to work from home. I currently have the following issues: 1. while using my Vista laptop, a USB to serial cable, PuTTY for terminal emulation, I can connect and after 1-2 minutes the connection quits. I restart PuTTY and it works for a short time. The router doesn't seem to know the terminal was restarted. I am using 9600,8,1,n Any clues? 2. I have a DHCP server and would like to disable the one on the SR520 3. While I do want to eventually create VPN's and perhaps VLAN's for now I would like to disable both and turn them on in stages. The config assistance is useful but I would like to preconfigure and make a seamless switch. My email is paladin@jwcomputer.net Thanks in advance, Jim Warriner

Jim,
It is recommended that CCA is used to configure the SR520. (Sure CLI can be used also of course, but CCA will build those firewall / VPN configs automatically for you).

Andrew,
Thanks, I was hoping to do this in stages and
configure as a basic router first and then configure
the VPN's.
Also I need to turn off the DHCP as I already have
one running with reservations for all the desktops.
I also need to disable the VLAN's and change the
IP for fe0 to the 192.168.1.0 (preferably to .1 but I will likely use .2)
We are in an operating work environment here and any disruption of the
internet is a major issue.

Sure - CCA will allow you to do all of this in stages to meet your requirements.
Connect your PC to one of the LAN ports and use CCA to connect with address 192.168.75.1 (this is the default LAN subnet used by the SR520).

Andrew,
Maybe I am dense but I am banging my head against a brick wall here.
I can g through the security setup wizard and get as far as "apply configuration"
but it is "grayed out" . I can save the config as a file but cannot find a way to
save te file to the router. Connecting to the router as you suggested does not
show an option for DHCP disable and gives warnings if I attempt to change the
IP address of fe0 stating that it will disable NAT.
What am I missing?
I have reset the ruter to defaults several times, connected to it with my vista
laptop in a "private network" (192.168.75.1 the router and 192.168.75,11 my PC)
and always run into the same issues. Obviously I am missing a step some where.
The router does nothave the wireless option so I am ignoring that section of the setup.
I doubt if I can return the router (not that I want to) because we received it via Techsoup
as a donation. I want to make this work.
