I am working for a laboratory which is situated in a university and we are currently part of the university network. I was recently made responsible for insulating the Laboratory LAN from this of the university aiming higher security. I am managing two servers (DNS, Mail, WWW, FTP, etc) but since I'm not a network professional I am looking for advice on a solution based on CISCO products.
Our LAN consists of about 35 units (PCs, servers, network printers, network cameras) all switched into a 20 port switch (additional switches are used along the way) which is then connected via fiber optics to the university network. All the devices have real IPs which have to be preserved. So I probably need a router which has
- a fiber optics port as input (or as a separate module?)
- possibly 20 100mbit ports as output
- built in firewall
- optional VPN support
Any suggestions would be greatly appreciated. Thank you!
