@antrikos_kal 

 You need route and you probably need NAT

route outside  0.0.0.0 0.0.0.0 gateway_ip

nat (inside,outside) source dynamic any outside 

[antrikos_kal]

ciscoasa(config-if)# sh route

Codes: C - connected, S - static, I - IGRP, R - RIP, M - mobile, B - BGP
D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area
N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2
E1 - OSPF external type 1, E2 - OSPF external type 2, E - EGP
i - IS-IS, L1 - IS-IS level-1, L2 - IS-IS level-2, ia - IS-IS inter area
* - candidate default, U - per-user static route, o - ODR
P - periodic downloaded static route

Gateway of last resort is not set

[Flavio Miranda]

Yes, I could see on the running-config that you have no route and that´s what I am suggesting.You need to identify which is your gateway and add the default route

You can try to identify the gateway by running the command "show arp" and "show ip arp"

route outside  0.0.0.0 0.0.0.0 gateway_ip

The NAT may be required may not, it will depend on how the ISP is handling this. They can be doing NAT for you already.

But, you need to have route.

[Aref Alsouqi]

You should get the default route from the ISP via DHCP, however, please check if that is the case with the command "sh route" or by pinging a public IP on the internet such as 8.8.8.8 or similar. If the default route is not getting injected by the ISP then as @Flavio Miranda suggested please add the default route manually.

Regarding NAT, you would need to create a dynamic PAT similar to this:

object network LAN
   subnet 10.1.1.0 255.255.255.0
   nat (inside,outside) dynamic interface

[antrikos_kal]

ciscoasa(config-if)# sh route

Codes: C - connected, S - static, I - IGRP, R - RIP, M - mobile, B - BGP
D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area
N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2
E1 - OSPF external type 1, E2 - OSPF external type 2, E - EGP
i - IS-IS, L1 - IS-IS level-1, L2 - IS-IS level-2, ia - IS-IS inter area
* - candidate default, U - per-user static route, o - ODR
P - periodic downloaded static route

Gateway of last resort is not set

it doesnt accept nat(inside,outside) dynamic interface wrong cmnd.

[Aref Alsouqi]

The NAT command I shared must be issued under the object network, not in global config.

Configuring PAT on an ASA (youtube.com)

But as @Flavio Miranda mentioned, you might not need it if the ISP is doing NAT for you although I don't think they do because they wouldn't have any visibility of your internal network. Also, if the ISP is doing NAT for your inside network when you add extra networks behind the firewall you either need to ask the ISP to NAT those ones as well or apply NAT on the firewall which I recommend.

[antrikos_kal]

if someone can connect via teamviewer i'd appreciate it.

[Rob Ingram]

@antrikos_kal you appear to be running ASA Version 8.0(5) which has completely different NAT syntax to the modern ASA. Refer to the Dynamic PAT example https://community.cisco.com/t5/security-knowledge-base/asa-pre-8-3-to-8-3-nat-configuration-examples/ta-p/3116375

Your outside interface is configured to receive an IP address and the default route via DHCP, I assume you get a DHCP address on the outside interface? You haven't received the default route (via setroute command), so you'd still need the static default route as already mentioned.

[Aref Alsouqi]

Very good spot @Rob Ingram.

[antrikos_kal]

Hi thank you all you guys my greetings from Greece, i recently lost my dad who was electronic engineer and was working in the national tv and the antennas.unfortunately he got cancer, but thank god he didn't have on bones or brain he died peacefuly on his sleep by cardiac arrest.When i will get better pshycologicaly i will try all the notes you gave me.God bless you all and away the sicknessess from you and your families.
