pix issue - how to

mor_feusz — Fri, 21 Feb 2020 08:18:45 GMT

Hello

I am trying to configure PIX 1st time in my life. My company (bought a

cabinet in datacentre). We hawe to set up connection

Datacenter send to us

set WAN port on Your PIX firewall

90.90.66.239 - 255.255.255.4

dafault gateway 90.90.66.1

set lan port on your firewall

90.90.67.112 255.255.255.248

Your default gateway (lan) will be 90.90.67.112

i tried to use wizard

and from interface outside i can ping world - from inside - no - i have a

laptop (configuration: 90.90.67.114, 255.255.255.48, default gateway

90.90.67.112)

In my opinion there is something wrong (90.90.67.112 is the network adress

we have arange of IP's 112 to 119 - 119 is broadcast address)

i set up

ip address outside 90.x.x.x 255.255.255.4

ip address inside 90.x.x.x.255.255.248

i doesnt work - i do not have internet connection

people have to ping me and i will have to ping them

mu configuration

type show route

check that your outside route shows 90.90.66.1 as the gateway.

by Default Ping is desabled on outside interface and pass through, create an access-list to passthrough ICMP.

set WAN port on Your PIX firewall

90.90.66.239 - 255.255.255.4

default gateway 90.90.66.1

i note you have corrected this netmask on the outside interface to 255.255.254.0

set lan port on your firewall

90.90.67.112 255.255.255.248

Your default gateway (lan) will be 90.90.67.112

your interface on the LAN side is also part of the subnet on the outside interface??

(90.90.66.0:255.255.254.0 = 90.90.66.0 - 90.90.67.254)

Strange config. Is that all the networks you have on the LAN side? I guess it would work but it's very confusing. You can't have a 'default' route on the both sides

It is strange for me as well - 112 is a network address

Byt i gaved up - i asked people from datacentre - they will charge and set up

I have no ideas how to do this 😞
