If the tunnel is to be terminated on this firewall device I would say look into a Mikrotik box. Alternatively you could make Cisco's IOS firewall / zone based firewall do this. So look into an ISR? Sent from my iPad On Jul 30, 2013, at 3:00 PM, William Herrin <bill@herrin.us> wrote:
Hi folks,
I'm trying to identify a firewall appliance for one of my customers. The wrinkle is: it has to be able to inspect packets inside an IPIP tunnel and accept/reject based on IP address, TCP port number and standard things like that. On the packet carried *inside* the IPIP tunnel packet.
From what I can tell, the Cisco ASA can't do this.
Linux iptables can (with the u32 match module) but the customer wants an appliance, not a server.
What appliances do you know of that can do this? Is there a different Cisco box? A Juniper firewall? Anything else?
Thanks in advance, Bill Herrin
