I made a simple pix config for inside to access internet,,,For tht we have purchased 6 prublic ip's from isp provider, i m using one of the ip

interface Ethernet0

ip address 202.63.101.68 255.255.255.248

interface Ethernet1

ip address 10.50.0.200 255.255.0.0

route wan 0.0.0.0 0.0.0.0 202.63.101.68 1

global (wan) 1 interface

nat (inside) 1 10.50.0.0 255.255.0.0

but some time people unable access internet tro pix.for that we have to chage the gateway in route command.if we give any one of the six ip's(public) in this gateway.it starts working..whre is the problem.? i checked all the public ip's with using single Pc dirctly without connecting pix.

Well, from looking at what you have posted -

Your using IP 202.63.101.68 on the outside interface of the PIX plus using the same IP for forwarding to the next hop WAN router i.e.

route wan 0.0.0.0 0.0.0.0 202.63.101.68

You need to change the forwarding next hop IP to something else i.e.

route wan 0.0.0.0 0.0.0.0 202.63.101.69 <--- THIS WOULD BE THE IP ADDRESS OF THE WAN ROUTER!!

Hope this helps and please rate posts if it does!

There must be some ISP default gateway - this gateway connects your network to Internet...Default route on firewall MUST point to this ISP gateway .. You should ask provider for your connection details..
