Firewall Server

We believe a good firewall is the backbone of security.

It is the first defense against data loss and infected workstations.

Iron Castle Firewall systems provide you with the highest level of security with the advanced features available, prevents, detects and cures potential security threats.
Our network firewalls protect your entire business. They block worms, stop hackers and prevent intrusion. Plus, centralized management and ease-of-use ensure proper configuration. Securing your business network and protecting data is simple and straightforward.

Main Features

Iron Castle Firewall was designed with both modularity and a high-level of flexibility in mind. You can easily deploy many variations of it, such as a firewall, a proxy server or a VPN gateway. The modular design ensures that it runs exactly what you’ve configured it for and nothing more. Everything is simple to manage.


The primary objective of our Firewall is security. As there is of course no one, single way to achieve network security, it is important for a network administrator to understand their environment and what the term security means in the context of their own network. I policies that manage each segment (see the Firewall page for more information).


• Filtering by source and destination IP, IP protocol, source and destination port for TCP and UDP traffic
• Highly flexible policy routing possible by selecting gateway on a per-rule basis (for load balancing, failover, multiple WAN, etc.)
• Transparent layer 2 firewalling capable - can bridge interfaces and filter traffic between them, even allowing for an IP-less firewall (though you probably want an IP for management purposes).
• Able to limit simultaneous connections on a per-rule basis

Network Address Translation (NAT)

• Port forwards including ranges and the use of multiple public IPs
• 1:1 NAT for individual IPs or entire subnets.
• Outbound NAT
• NAT Reflection - in some configurations, NAT reflection is possible so services can be accessed by public IP from internal networks.

Load Balancing

• Outbound load balancing is used with multiple WAN connections to provide load balancing and failover capabilities. Traffic is directed to the desired gateway or load balancing pool on a per-firewall rule basis>br/>• Inbound load balancing is used to distribute load between multiple servers. This is commonly used with web servers, mail servers, and others. Servers that fail to respond to ping requests or TCP port connections are removed from the pool.

VPN Server

• Iron Castle Firewall offers three options for VPN connectivity IPsec, OpenVPN and PPTP

Web Proxy

• Full-fledged web proxy, which is used by ISPs, universities, schools and large companies networks. In addition to the stateful paket inspection (SPI) filtering by the firewall on the TCP/IP layer, the web content which is transmitted over HTTP, HTTPS or FTP can be analyzed and filtered as well.

Content Filtering

• Block or restrict Internet content conditionally by time, user and/or computers.
• Preventing access to certain (eg. youth-endangering) pages and content categories.
• Hiding advertising. Intrusion detection system DHCP Server AND MORE ...
