Hi,<br />
I have an ISA server sat behind 3 different firewalls connected to the internet by a cheap netgear adsl router.<br />
<br />
I need to pass 443 traffic from several 3g connected laptops to/from the ISA server.<br />

I can use NAT on the ADSL router but not elsewhere.<br />
Can I do this with a simple routing rule on each firewall?<br />

Hi,
I have an ISA server sat behind 3 different firewalls connected to the internet by a cheap netgear adsl router.

I need to pass 443 traffic from several 3g connected laptops to/from the ISA server.

I can use NAT on the ADSL router but not elsewhere.
Can I do this with a simple routing rule on each firewall?


Routing 443 through multiple firewalls

Software firewalls, also known as host-based firewalls, provide a layer of software on one host that controls network traffic in and out of that single machine. Most operating systems now include firewall software, but many available software firewalls include central distribution, antivirus systems and disaster recovery.

Software Firewalls

Microsoft Forefront, formerly known as Internet Security and Acceleration Server (ISA Server), is a network router, firewall, antivirus program, VPN server and web cache that runs on Windows servers. It includes identity management and protection systems, and discontinued systems for threat management and network protection, along with protection for Sharepoint and Exchange. The scope of discussions includes forward and reverse proxy, application and service publishing, virtual private networks (VPNs), outbound access rules, SSL certificates and network routing within either a single node or an highly-available array pairing.

Cisco PIX is a dedicated hardware firewall appliance; the Cisco Adaptive Security Appliance (ASA) is a firewall and anti-malware security appliance that provides unified threat management and protection the PIX does not. Other Cisco devices and systems include routers, switches, storage networking, wireless and the software and hardware for PIX Firewall Manager (PFM), PIX Device Manager (PDM) and Adaptive Security Device Manager (ASDM).
