RE: PIX Question

["John Canty" <John.Canty () Vibro-Meter com>]

Believe it or not, this does seem pretty rock solid advice. So the next
question would be what steps would one take to protect the perimeter
router???

Thanks,

You need no protection.  The PIX will withstand what is put against it.
All the advice you are receiving about BDS fw, IOS FW and the like
doesn't 
address your specific need.

Key being.  You are terminating IPSEC.  You put another FW in front and
you 
risk losing the IPSEC.

I work with PIX daily.  It needs no protection.
Telnet:
As far at telnet (you cannot telnet to the outside of a PIX- impossible)
PDM:
Set up access via the command: http <host_IP_address> 255.255.255.255
outside
for each host you want to have access from.
Better yet, open none of that and VPN to the PIX and then use 
telnet/ssh/pdm from inside the VPN tunnel.

Don't run CBAC unless you have a 3600 series router or above.

If you really want protection that the PIX does not provide, get your
ISP 
to limit the ICMP traffic to a max of 20 % of incoming traffic. help 
protect against DDOS

Got questions, email me offline
