can't ping ASA 5510 from other subnet

                   Background:  I have a couple of ASA 5510's I'm going to put in our lab environment.  I have restored them to default config and set up the m0/0 interface with an ip/mask and started the http server.  My lab environment is on the 10.45 subnet and my .com corporate environment is on the 10.40 subnet.  I've also setup DNS and, from the ASA, can ping anything in the 10.45 subnet.

The problem, is that from the ASA, I can not ping the internet or my 10.40 subnet.  And vice versa, I cannot ping the ASA from my 10.40 subnet.  When I bring up a regular server, there is no special configuration I need to do as those subnets talk to each other and nothing is restricted.

Is there something special I need to do go get it to work?  I tried adding a access list to allow icmp, but that didn't seem to work.

Oh, and I'm getting to the ASA by RDPing into a lab server (on 10.45) then putty to the ASA.

Any thoughts or suggestions are appreciated.

Thanks

Re: can't ping ASA 5510 from other subnet

Hi,

I cant see any of the usual interface configured. Only the management?

There is also no route through the management interface for networks belonging to range 10.40.x.x/yy

The management interfaces network range also doesnt include networks 10.40.x.x/yy

EDIT: You can remove the "http" configuration lines with command "no" and the configuration line you want to remove.

Correct, I only reset it to default and am only getting the mgmt interface up.

How do I make the route and other correction?

Thanks

Hi,

Basic configuration format for routes is

route

Where

  • interface nameif = Interface name configured with the "nameif"
  • network address = Network address of the remote network you are making route for
  • network mask = Network mask of the remote network you are making route for
  • gateway address = The next hop IP address behind which the network is found
    • Since the network in question isnt connected directly to the ASA there must be some router (gateway) behind which the network is found.

I think it worked, but I'm unable to check right now since I am remote.  I could test if I also enable ipv6 to run in conjunction with 4v.  Any advice on how to get that setup?

Thanks
