ASA 5505 static IP

[cfecadministration]

Hi,  I have been playing with my new ASA 5505 for a few days now.  After I got over working out how to use the ASDM with Windows 7 I am starting to work out its foibles. 

If I clean the ASA up with factory default via the Command Line Interface it work fine on the outside with the DHCP provided by my internet providor.  BTW, I am in a managed office in the UK within another private network with a 10.XX.XX.XX LAN.  We have public static IP addresses which is mapped to a 10.XX.XX.100 number.  So, in other words with a clean install and both inside and outside using DHCP everything works great, all my 192.168.XXX.XXX LAN addresses can access the tinternet via the 10.XX.XX.1 gateway.  All hunky dory. (NB with Windows 7 using ASA 8.3 version the start up screen will not work using any browser, I had to take it of the bundle disk)

When I use the startup wizard to make the outside interface have a static address of 10.XX.XX.100, I have given it DNS server addresses 195.171.X.XX etc,

I have on the inside interface given access to HTTP and DNS (port 53).

But the plain fact is if you use it with DHCP on the outside it works.  If you use it with a static address it does not, I get the yellow problem marker on my network icon in the sys tray.

Any suggestions ??

Hi,

I suppose OUTSIDE is WAN interface so you should give it a public IP address and not one from the private 10.0.0.0/8 range.

effectively the 10. number is the WAN.  The public IP is mapped to 10.XX.XX.100

Also, if I set the last DHCP that worked on the outside interface that does not work either on static setup.

Hi

Can you tell us what ip address you get when you use DCHP?

outside interface connects with 10.35.45.14 when in DCHP

I am trying to set up the outside interface with static address 10.35.45.100

What about using the dhcp address as static one? what happens then?

Regards.

As I said above, if I use the address provided by the DHCP i.e. .14 it is the same, it does not work, there is no access to the internet.

Can you do sh  ro static when dhcp and configure this route when in static as  I suppose this is the problem.

Regards.

Alain.

Would you like to say that in English ??

[N W]

I think he means Show route static

.

Can you use packet tracer? That will tell you where the issue may lie and what may cause it.

No route to host

there you go. add in a default route.

conf t

route 0.0.0.0 0.0.0.0 (next hop)

[cfecadministration]

Success, thank you all.

What was also messing things up earlier was the NAT was not set.

Thanks again, see you all when I try to set up the VPN.
