Hi, I will have to contact

Bighead81 · ‎02-07-2015

Working with an ASA 5505 that is not allowing me to connect to the internet.

I am able to ping desktop PC inside interface but from the firewall not able to ping outside to 8.8.8.8.

Ive troubleshooted with outside interface ip DHCP routeset, icmp session,

Any help to correct this would be appreciated.

Hi,

It looks like there is an issue with NAT. try the following.

1) remove the following statements with 'no' followed by the command

object network obj_any
subnet 0.0.0.0 0.0.0.0

and

nat (inside,outside) source dynamic obj_any interface

2) now add the following

object network 192.168.0.0_net

subnet 192.168.0.0 255.255.255.0

nat (inside,outside) dynamic interface

Hope this will help.

regards

reddy

Bighead81 · ‎02-08-2015

Thanks for the response.

I removed and added your recommendations and then had to add route outside 0.0.0.0 0.0.0.0 7.x.x.1 (default gw isp)

Still no outside ping!

David paull · ‎02-08-2015

object network NAT_ALL
subnet 0.0.0.0 0.0.0.0
nat (inside,outside) source dynamic NAT_ALL interface

That will nat anything from inside to your asa's external interface IP...in asa 8.4, not sure how the wording is in 9.1

When you say you added a default route -- did you make that default route point to the next layer 3 hop?

Can you ping the next hop from your ASA? can you ping the external interface at that next hop device?

Can you do the following on your asa

access-list CAPNAME extended permit ip any any

capture CAPIN interface inside match access-list CAPNAME

capture CAPOUT interface outside match access-list CAPNAME

That would be nice to see the request going to the inside interface, being translated, and leaving the outside interface as the NAT'd ip address. Running those capture, then a ping from the host to 8.8.8.8 (just 4 is fine) then posting show cap CAPIN and show cap CAPOUT will probably solve our issue, or at least really narrow it down by telling us where to look.

Bighead81 · ‎02-08-2015

The default route ip is the default gateway of my ISP. When I connect modem directly to PC I get connection and I can see DGW and assigned ip address. This has remained static as both FW and desktop have been assigned the same MAC.

Not able to ping anything at all after ASA

I have added capture.

Opened port dhcps port and seeing capture below.

Hi,

Can you ping 8.8.8.8 from the FW itself?

Some ISP's bind the MAC address to devices and only those devices are allowed to communicate to outside world. If that is the case, you need to ask them to clear the arp and give them the ASA FW mac address to register. ( are you getting IP address for outside interface? looks like DHCP client is enabled on outside from the above)

If you manually configure primary DNS on the PC to 8.8.8.8, Can you reach internet from internet explorer?

Can you use packet trace from ASDM and select the interface as inside and protocol as tcp source port as 2005 ( or any random port) and destination ip : 216.58.208.46 and destination port as: 80 and post the result here?

Also please post the results of >

show nat

show run nat

Bighead81 · ‎02-08-2015

Hi,

I do have is ip address bound to my mac address, which has given me the same ip address and will continue to do so which is 7.x.x.239 (default gateway is .1 of this) but I have applied dhcp setroute because of ISP.

Hi,

Can you not apply the inside ACL and see what happens?

also can you change

nat (inside,outside) source dynamic NAT_ALL interface

to

nat (inside,outside) source dynamic interface

you don't need to say NAT_ALL in nat statement.

David paull · ‎02-08-2015

So you're showing NO ip traffic entering your ASA.

And you're showing ip traffic leaving your ASA from 0.0.0.0 destined to 255.255.255.255.

Clearly your NAT is not working.

Bighead81 · ‎02-10-2015

Ive troubleshooted the following -

Erase all / fresh config

ACL any4. You now have to specify ipv4 or ipv6 for any

inspect traffic dns, http

Reapplying DHCPD config for inside

Permiting ICMP traffic [echo, unreachable, time]

Recommended nat statements

object network obj_any
   subnet 0.0.0.0 0.0.0.0
   nat (inside,outside) dynamic interface

Cisco recommends the above.

I have attached latest config.

When I do a packet trace for internal source ip to isp default gateway with dhcp ports it says ok- same for internal to google.com OK again

Im going to leave the firewall on in the mean time and leave it on for 24 hours. ISP clear their ARP in the early hours
My mac address is bound to the same ip, which i have assigned both to FW and PC.

I also bypass the switch and the computer can king default gateway but nothing on the isp interface or default gateway.

Any other ideas?

It's still not natting. You have packets leaving from 0.0.0.0 to 255.255.255.255

--

object network 192.168.0.0_net
 nat (inside,outside) dynamic interface

You need to define what is INCLUDED in the object network NAMED 192.168.0.0_net

so

object-group network 192.168.0.0_net

network-object 192.168.0.0 255.255.255.0 !or whatever your subnet is

nat (inside,outside) source dynamic 192.168.0.0_net interface

That WILL nat your traffic to the external interface.

I know you think you created a range, and you did with your range statement but you never called it with:

network-object object NAMEHERE

Bighead81 · ‎02-10-2015

I have tried that nat statement (quite a few times) and its still not working.

Object group contains 192.168.0.0 / 24 and 0.0.0.0 0.0.0.0

When I connect desktop I have been assigned the correct 192.168.x.x internal ip with gateway but cannot ping or surf web. From computer I can ping inside default gateway and nothing else.

David paull · ‎02-10-2015

I won't be back until tonight. Can you post:

1) Your updated, newest, current configuration?

2) clear cap capin

3) clear cap capout

4) Ping from an inside device to 8.8.8.8.

5) and then also put up your newest captures (capin and capout)

If you change your config between posting and tonight, back it up so that any changes I can help you make can be put in.

Thanks!

Hi,

again you got the NAT statement wrong

>>>nat (inside,outside) source dynamic INSIDE_NET interface

this should be

nat (inside,outside) source dynamic interface

and the above should be with in the object group/object as shown below, please add them one below the other, but remove the old one's before you put the following

object-group network INSIDE_NET
network-object 192.168.0.0 255.255.255.0
nat (inside,outside) source dynamic interface

regards
