Firewalls

NewNet is able to offer a full range of firewall services through its own devices. A dedicated NewNet firewall can help to protect against:

• IP spoofing
• icmp and DoS attacks
• Known ports which are used for hacking
• Windows file system ports
• Port scanning

With up to 100% availability guarantees, NewNet IP Transit is the ideal service of choice for any company demanding high availability with high bandwidth and low latency.

NewNet is able to offer a range of services – from application of basic rules to fully managed firewalls. Firewall rules can be applied to deny or grant access to a specific IP or port address:

• Allow udp/tcp from {secure-range} to {server-range}
• Allow tcp from {any-iprange} to {server-range} port {www-port}
• Allow tcp from {ftp-admin} to {server-range} port {ftp-port}
• Deny udp/tcp from {any-iprange} to {server-range} {window-fileshare}

A range of rules can be applied to deny general access but to grant access to specific ports and or from specific addresses – it can be useful for example to allow ftp access to a server but only from a nominated address. Firewall rules can be set up to deny general access to Windows filing system ports. NewNet is also available to give customers advice on firewall set-ups, based on years of industry experience.
