I plan on connecting two LANs together via. the internet (public resource). The LANs are across town.
The computers on each LAN will be able to access other(some) computers on the other LAN (and vice-versa), they will still be able to connect to the internet. Basically, they will be able to share resources (files, application etc.)
Undergone some research regarding this, was able to find out that having a VPN connection will be a good way to go. But I have no full knowledge on what hardware I will need. How to start exactly.
If VPN is actually a good way to go, please let me know (maybe some other alternatives).
If I can get a good picture of what to do, will be very happy.
Please, can someone lead me in a good direction. Thank you.
first using a public network like internet without any security i mean encryption is not recomemded ,what i would suggest is to use a VPN tunnel between both sites,so you can configure your routers with the appropriate ios software to build the tunnels, but if you have to connect a huge sites the best way to go is the use of a VPN concentrator 3000 series, if one of the two sites has less that 250 client you can use a client VPN concentrator 3002 series .
First of all lets focus on the end points connectivity part.What is the internet terminating onto?Say if its a leased line or a Ethernet or ADSL, then you can directly terminate it onto a cisco router.If its a ethernet connectivity, then I would recommend PIX or ASA.
Secondary we come to the tunnels,i.e, the link between both the offices which should be encrypted.This tunnel will be your pipe.Though a PIX/ASA by default support VPN tunnels and encryptions,you need to have that K9 IOS into the router.
Pls eleborate on the connectivity medium, then it will be easier to suggest you something.
Pls read the text at following link...it will give you a better picture...
I recommend using an IPSec tunnel. You can do that easily "not complex", since the leased line is expensive, you can install cisco 1841 with ADSL WIC "this depends according to your DSLAM" in each site and install an advanced Security IOS image on the two routers and start playing. i think this solution will help you connecting the both sites.
Secondary, to my knowledge,SSL VPN is "per user" based.That is you cannot route whole branch's traffic using one single tunnel.Every user in the remote branch will have to initiate a tunnel seperately.Hence, if u have 50 users, then u will have 50 seperate tunnels.
If costs prohibits then not I nor u can do anything about that. A cisco 2800 series router supports upto 75 SSL VPN connections.
We have 3 identical switches configured by someone else and would like to claim some of the Gigabit ports(G1/G2/G3/G4) for use on servers. When we try to change the wiring and configuration, we run in to connectivity issues. Attached is a des...
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
