I have just put on 5 Telstra highspeed ADSL connections in remote locations and i need to prepare my self before i fly to each site to configure these connections to work with our current VPN set up.
Telstra have supplied Cissco 850 routers for each connection.
What i need to know is in the next 2 weeks all my locations will have Cisco 850 routers and my head office will have a cissco model 1800 router for BDSL.
Do i set these routers into bridge mode and let my current Snap gear 530 boxes do all the authentication and VPN Ipsec tunnels like i previously had set up, or do i do away with the SG530s and let the cisscos do all the work.
My old network had normal ADSL connections with a adsl modem set to bridge mode passing all the authentication to the SG530s.
I then had IPsec tunnels set up between each location.
I have a server 2003 DC in each location and my main server 2003 DC (Global Catalog) is where the cissco 1800 will be located.
I am only new to networking, never used cissco devices before and with the previous net set up i had, i stumbled my way through it with the advice of a helpful guy from a small computer shop.
Whats the best sollution

Thanks

If you have the VPN tunnels already working, why bother redoing them all?  If you are happy with the current set up and as you are not very familair with Cisco devices, save yourself the headache and have the Cisco's bridge and be done with it.

Honestly, it depends on your personal feelings about it all - I would be more inclined to get rid of the SG530's to eliminate another point of failure and make my life overall slightly easier. Cisco VPN is quite easy and there are a few ways to do it.

getting rid of the sg530s was what i thought would be the best. im not very familiar with cissco but i thought the quality and security was supposed to be the best.
Plus its a very good point about one less thing to fail.
Can you use a web interface to configure them or do you have to do it via a command line.
Thanks

You can use the web interface, however IOS is worth getting used to.

Here are some references to get you started - but the gist of it is, set the same VPN settings on each end and you're fine (except peer, of course):

Highfive + Dolby Voice = No More Audio Complaints!

Poor audio quality is one of the top reasons people don’t use video conferencing. Get the crispest, clearest audio powered by Dolby Voice in every meeting. Highfive and Dolby Voice deliver the best video conferencing and audio experience for every meeting and every room.

Another option would be to approach your service provider and ask if they have a Private IP or MPLS-VPN solution.

Or console/ssh/telnet in and perform the following, -after- you've made your changes:
enable
copy run start

I got rid of the sg530s and set up my VPN tunnels
took a bit to get my head around the way cisco do things, but it worked.
The next step is getting all the firewalls running and secure. Any advice

Thanks
