Cisco Firewall :: Access And Ping Inside Interface Of ASA5505 From Remote Network?
Sep 13, 2012
I am trying to access and ping the inside interface of a ASA5505 from a remote network. From the remote network, I am able to access anything on the local network, but the ASA5505 inside interface.The 2 networks linked by a fiber link which have a transport network on another interface. From the remote network, I am able to ping the transport network interface IP, but I would like to be able to ping the inside interface IP. When I do a packet tracer, I get a deny from an implicit rule.How can I achieve that?
Here are the subnets involved and the ASA5505 config.
Remote network : 10.10.2.0/24
Local network : 10.10.1.0/24
Transport network : 10.10.99.0/24

I've recently upgraded my old firewall from a PIX to an ASA5505 and have been trying to match up the configuration settings to no avail. I have is that I can't ping the new firewall on it's inside interface, despite having "icmp permit any inside" in the running config. Secondly, the server I have on there ("Sar") can't connect out to the internet.I've included the ASA's running config incase anybody can see if something stands out. I have a feeling it's either not letting anything onto the inside interface, or there is no nat going on. Lastly (and possibly relevant), the firewall is actually going at the end of a vlan, which is different to the firewall's inside vlan number. I don't know if this is actually the problem because the server can't connect out even if connected directly into the firewall.

I'm trying to make a very plain and simple network with the ASA 5505, I've strated from scratch over a dozen times triyng to find where I'm going wrong. My main goal is to simply create an IPSec VPN connection to my ASA 5505 and simply ping and connect to devices with the "inside network", so far I can easily create and establish a IPSec VPN Connection, but up to this point, I cannot successfully ping or access a single device on the ASA 5505 inside network.I've taken, create the IPSec profile with the ASDM wizard, add exemption for the VPN IP Pool, add access-list from this Cisco link, url...All this and I can't make a single connection to the inside network.

I just try to ping a internal Host but it want to go.
Laptop<===>ASA5505
Connected is the Laptop at Ethernet 0/2 Inside
My running-config is a clear config, only VLAN 1 has a IP and Ethernet 0/2 is up.
But If I try to ping to the Laptop I get the followed:
asa5505# ping 192.168.1.100
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 192.168.1.100, timeout is 2 seconds:
?????
Success rate is 0 percent (0/5)
asa5505#
From the Laptop to the ASA5505 I can Ping successfully.

I have ASA5505 configured with internal network as 192.168.15.0 and default gateway 192.168.15.1 From the inside network, i'm able to access internet and able to ping all website (enabled ping). and all internel network devices can ping each other. Except i cannot ping my gateway (ASA5505) 192.168.15.1. I'm continously seeing this message on the log, when i tried to ping.. How to fix this?
Denied ICMP type=8, code=0 from 192.168.15.xxx on interface inside
replace xxx with my network devices that try to ping the gateway..I dont want outsiders ping my gateway, i need ping for inside internal network only.

I have been working on a configuration for single IP address (on outside ) of ASA5505.I am trying to utilize the outside address 192.168.0.249 to PAT/NAPT to 10 inside machines [code]
What I am not sure of (actually that could be considered all encompassing) is the mapped services/real services.Any constructive comments assistance?

I have a ASA 5505.|I configured it for remote access VPN from cisco VPN client.the ASA receives a public ip address on outside interface via PPPoE.I can connect to public ip of outside interface and address 10.1.1.2 is assigned to my Cisco vpn client.the problem is that I Cannot ping or reach ASA internal IP address 172.16.29.1 in any way when I am in VPN from outside,while I Can ping other hosts on 172.16.29.0/24 when connected in VPN.this is a problem brcause when I am connected in VPN to ASA I Cannot configure it..Then I Wanted to ask if it is possible a configuration which gives addresses from network 172.16.29.0/24 (the same as inside network) to VPN clients instead of another network (10.1.1.0/24) [code]

I have an ASA 5505 that I'm trying to set up a guest network on. I've configured an interface as a trunk and allowed the 2 vlans but I'm not getting any layer 3 to it. The switch connected to it is a 3560 and port is configured as a trunk with the same vlans.
I can't ping the ASA inside interface but I see its MAC address in the swtich's table.

The ASA is configured in very simple transparent mode. As desired, traffic can flow in each direction between inside and outside. I can manage the ASA via console and direct connection to the management interface. The problem is that I cannot ping or ssh to the ASA via the inside interface. I need to be able to manage the ASA from any PC on the inside LAN. I suspect I am missing some easy aspect of the configuration but after a lot of hours I'm about at the end of my patience with it. Here is what I believe to be the relevant parts of the config.
ASA Version 8.2(1)
!
firewall transparent
hostname issr1
enable password 2alej83t5cqT0FWd encrypted
passwd 4kleUY438I93.4ljdh encrypted

Using an ASA5505, have 1 static outside address, want to access an inside SBS-Server on SMTP, RDP (3389), HTTPS and port 987
Have configured network object nat rules using the asdm, SMTP works (I can telnet to the server on port 25 from outside), however for some reason I can not telnet inside and out on port 25, so outgoing mail does not work. RDP does not seem to work from outside, 987 I havent tested from outside. When I try to create a network object nat rule for https I get this message from the ASA:
[OK] object network SBS-HTTPS
object network SBS-HTTPS
[ERROR] nat (inside,outside) static interface service tcp https https
NAT unable to reserve ports.

I am using ASA 5505 firewall with base-license. I connected my firewall to one cisco 3750 switch where i created 5 vlans. I done NATing for all vlans and they able to get internet and working fine. They able to browse all internet sites like gmail and yahoo mail.
All internal users are configured to use Outlook for their webmail. Here the problem is with outlook they are unable to send and receive the mails.
If they directly connected their system using public ip( Directly from ISP) they able to send and receive mails from outlook.

I have an issue accessing the inside network of my church from VPN. This only happens when I connect from my home network. I have no problem accessing inside network of my church if I'm connected from else where (my Clear Hotspot or someone else's house). Here is the hardware detail:
At the church, we are using Cisco ASA 5510 and we have so many VPN tunnels to different churches. At home, I 'm using Cisco ASA 5505. See that attached configuration for my home ASA5505.

I have a Cisco ASA 5505 and I have my internal and external interfaces configured but I currently cannot ping from the inside to an IP Address on the outside. I had this setup and working and I have another set of equirement that I am replacing that is working with my service provider so I know it is a configuration issue. When I ping 4.2.2.2 for example I get:
Destination host unreachable
Do I need to add a static route from my inside interface to my outside interfaces?

I have been asked to set up remote access VPN on an ASA 5505 that I previously had no invlovement with. I have set it up the VPN using the wizard, they way I normally do, but the clients have no access to anything in the inside subnet, not even the inside interface IP address of the ASA. Thay can ping each other. The remote access policy below that I am working on is labeled VPNPHONE, address pool 172.16.20.1-10. I do not need split tunneling to be enabled. The active WAN interface is the one labeled outside_cable. [code]

I currently have an out of the box ASA5505 and need to change the internal interfact from 192.168.1.1 to 10.20.3.1 so it fits in with the rest of the network.Tried using the ASDM Startup wizard (via 192.168.1.1) and it just seems to hang on "delivering the commands to the device".

I did this on the PIX and it worked like a charm, but I am having some difficulty translating the configuration to an ASA.
In the PIX I performed NAT on outside traffic to a specific inside host (web server) to map to the inside interface so that return traffic would go to the same firewall the traffic came in through, The reason for this configuration was because the gateway of last resort was a different firewall and not the firewall the traffic came in through.
Now to further give you some history, the gateway of last resort is an ASA running 9.1 (Now), prior to that it was a PIX with v8.0(4), traffic to the aforementioned web server came in through the gateway of last resort), which at the time was the PIX.
However, for some reason after swapping the PIX for an ASA (same rules, updated NAT rules for 9.1) access to the same web server is slow. Not sure why, but it’s the case. To alleviate the slowness we experienced, and until I can figure out why this occurs on the ASA, I placed a PIX on the network that only listens for traffic for the web server in question. On this PIX I map to the inside interface so that traffic flow works and external clients can access the web server with no issues.
So two questions, one I would like to use the configuration I have for the web server on the PIX on the ASA to see if that setup on the ASA works better, but having difficulty translating the rules to the ASA.
Second question, (Slow access with ASA to a web server, but fast with PIX to the same web server)?
P.S. Addresses in attached picture config are not real, but I know what they translate to.

we have a server that has an outside IP and an inside IP. It's inside ip is 192.168.222.30/24 and it's outside IP is 199.204.50.2/29. The connection to this server from the outside is perfectly fine, but access from inside users to the NAT'd IP which is 199.204.50.2/29 is having issues, however, access to the inside IP works fine (this part makes sense)Will It be a must to set the inside DNS A record to the inside IP and not the outside IP, or can users on the inside interface access the NAT'd IP which is assigned to the server
LAN(192.168.222.0/24)<=====>InsideASAOutside<=====>(Server with NAT IP 192.168.222.30/24, it's also physicall assigned to this server).This is an ASA 5510 with 8.4.

I cannot get this to work properly and I've even had a Cisco engineer from TAC set-this up... and it literally broke my inside network. I have a VPN range of addresses..x.x.x.x on the Outside that needs access to a server on the Inside at y.y.y.y. HTTPS/443 connectivity. I need to NAT my VPN subnet/pool in order to talk to the inside host, as that host will not accept traffic from my VPN subnet, but obviously, will accept traffic from Inside my private network.
The Cisco tech entered the following static NAT statement to "fix" the problem - nat (outside,inside) source static VPN Inside-Network destination static Host-y.y.y.y Host-y.y.y.y For whatever reason, whenever this is configured on my ASA 5550 v8.3(2)25 the Inside interface starts proxy arping and assigns all IP addresses on my private network with the MAC address of the Inside interface.
The y.y.y.y is on a remote, routed network within my private, corporate MPLS network. My Inside private network (Inside-network shown in the static NAT above) is x.x.x.x. Not sure why this happens, but it kills my entire network and I have to jump through hoops to quiesce the network and get everything back to normal.I've tried to Dynamic-PAT/hide the VPN range behind the Inside interface through ASDM and that seems to do nothing.The NAT statement above will break my network. How to NAT this connection without killing my Inside network? Or, on how to properly hide my VPN subnet/pool behind my Inside interface and back to the VPN subnet/pool.

I have setup a Remote access VPN on my ASA5505 firewall through the ASDM wizard.I can successfully connect with the Cisco VPN client. My firewall also shows me the VPN session and shows incoming Rx packets. However, Tx packets remain 0, so no traffic is going out. My ASA5505 is configured as router on a stick with 25 different VLAN's. I want to restrict traffic to one specific VLAN using a crypto map.When I issue a ping -t command on my connected Windows box, the firewall log shows me the following message:
"IKE Initiator unable to find policy: Intf outside, Src: 10.7.11.18, Dst: 172.16.1.1."
"This message indicates that the IPSec fast path processed a packet that triggered IKE, but IKE's policy lookup failed. This error could be timing related. The ACLs that triggered IKE might have been deleted before IKE processed the initiation request. This problem will most likely correct itself." [code] I have really no idea what's going on. I have setup a Remote access VPN countless times but this time it shows me the error as described above.

My internal network consists of Catalyst 3750 switches segmented into different VLANs. There is a default route on the layer 3 Catalyst switch sending all unknown traffice to the inside Internet of the ASA 5510. However, I'd like to have a separate VLAN for wifi guest access and send all of that traffic through one of the DMZ interfaces on the ASA 5510. I don't think you can have separate default routes based on VLANs on the 3750 switches so my only option is to make the ip address of the DMZ port the default gateway for all hosts on the wifi guest VLAN.
The problem I have is that I have a couple servers behind the inside interface that have services available to the public Internet via a NAT address on the outside interface. I want the guests on the wifi VLAN to have the ability to access the servers on the inside interface using the public address as well, but have not been able to come up with a solution yet.
Here is my config that pertains to this setup:

I've tried the following commands below but no dice.
