Cisco Firewall :: ASA 5520 - 106001 Syslog Events For Internal Hosts?

Jul 26, 2011

I've just taken over a new network with a Cisco ASA5520. Everything is working fine, except I am being bombarded with 106001 alerts from a few internal hosts to one specific internal host. The description in general is "Inbound TCP connection denied from 10.1.0.1 to 10.1.0.5 - both of those are valid internal hosts and the TCP ports are also valid. I tried looking at the log and getting it me to tell me which rule was causing these alerts, but it just came back with 'It's not possible for these type of alerts'
 
- How is it possible for the ASA to even pick up on this when, in theory, the source host wouldn't be going near the ASA since it's on the same subnet?

- What might be causing this?

- How can I turn it off!! (I guess that'd be fixed by point 2)

Cisco Switching/Routing :: ASA 5505 - Dynamic And Static Internal Hosts Setup

Nov 21, 2012

I'm working on setting up a template configuration for the Cisco ASA 5505 device that we'll use to configure more routers for various client needs. One of the requirements requested of me is the following: Internal hosts assigned a DHCP address are blocked from the internet Internal hosts with a static IP are permitted access to internet All internal hosts can communicate regardless of state
 
Now, I'm fairly new to this and I'm certain my terminology isn't correct so googling the problem has been fruitless. I have followed basic configuration guides and have configured the device to hand out DHCP addresses to hosts plugged in ports 1-7. If I'm plugged in and specify my address manually in the OS I am blocked from any access so I can only assume there is an access policy or some rule preventing me from authenticating against the router despite having set up VLAN1 to be the entire class C subnet. What sort of steps would I need to do to configure this? New access lists. For the record, the dhcp addresses are in the range of 10.100.31.64-10.100.31.95. VPN users are assigned an address from 10.100.31.220-10.100.31.240 and there seems to be no issues with that configuraiton. I don't wish to constrain what addresses a user can use should they specify a static IP (10.100.31.5 should be just as valid as 10.100.31.100).

Cisco Firewall :: Statically PAT Multiple Internal Hosts To One External Host 5510

Feb 20, 2012

I am working on replacing our Checkpoint Firewalls with ASA's, and am running into the following NAT problem. On some of our Checkpoints, there are external NAT's that are mapped to multiple internal hosts based on ports.Is there any way to translate that to the ASA? I'm not sure the ASA will let you have multiple internal hosts mapped to one external IP using static NATs. The main issue, is these are alarm panels that receive data from external hosts (the traffic is initiated externally on the Internet) so I can't use dynamic PAT with this.

Cisco WAN :: 2800 Setup Router To Resolve Both Internal / External DNS Requests

Jun 3, 2012

I have a 2800 with one Gigabit interface connection to our Lan and the other interface connected to the internet with a public IP address. Now I'd like to setup the router to resolve both internal and external DNS requests. Thus requests like www.google.co.za and LocalLanPcName should be resolved to their public and private IP's respectively. [code] When I ping any name the only DNS server that is ever queried is 192.168.1.200 (it does resolve internal name correctly though).

None of the other servers are attempted to resolve the name. It does not matter if I specify a FQDN or not.
 
How do I setup the router so that my internal resolution is handled by 192.168.1.200 and .201, while external resolution is handled by 41.160.36 and .37. Or alternatively, how do I configure it to at least try all 4 specified name-servers for resolution, and not fail after trying the first one unsuccessfully.

Cisco WAN :: 1800 Cannot Connect Or Ping Hosts On Other Side

Jul 13, 2011

I have recently bought two 1800 cisco routers and have tried to connect them over wan serial link, but I am having problems when trying to access resources on the other side. I am a newbie to cisco and I wonder if the problem is with the configuration or the new routers or the serial link between the sites. Below is the show-running config results I have done on both routers; I can ping the serial interfaces from both sides and remotely, but I can't ping hosts or FE from other side.

Cisco Switching/Routing :: 2 Routers 2611XM No Ping Between Hosts In Each

Mar 18, 2013

I've set up a simple lab network of two cisco routers 2611XM and to each router I've attached a computer (host). I have set up a dhcp ip addresses for each host. I've set up a correct routing as well on each router. There are 3 networks:  192.168.1.0/24 192.168.2.0/24 192.168.3.0/24 The first network between the first host and first router, second is between two routers and third is between the second router and second host. If I use first host (192.168.1.20) I can ping to any ip address (192.168.1.1 (router 1), 192.168.2.1 (router 1), 192.168.2.2 (router 2), 192.168.3.1 (router 2)) except the second host ip address which is 192.168.3.20. When I sit on the second host (192.168.3.20) i can ping to 192.168.1.1 (router 1), 192.168.2.1 (router 1), 192.168.2.2 (router 2), 192.168.3.1 (router 2) but i can't ping to the first host which is 192.168.1.20.  I've even tried with attaching a switch to a router and assign it an ip address of 192.168.1.3 and the ping was echoing to it.

Cisco Firewall :: ASA 5505 - Cannot Ping Local Traffic And Hosts

Jul 24, 2012

I have, what I believe to be, a simple issue - I must be missing something. Site to Site VPN with Cisco ASA's. VPN is up, and remote hosts can ping the inside int of ASA (10.51.253.209). There is a PC (10.51.253.210) plugged into e0/1.

I know the PC is configured correctly with Windows firewall tuned off. The PC cannot get to the ouside world, and the ASA cannot ping 10.51.253.210.

I have seen this before, and I deleted VLAN 1, recreated it, and I could ping the local host without issue. Basically, the VPN is up and running but PC 10.51.253.210 cannot get out

Linksys Wireless Router :: E4200 Could Ping But No Connection On Any Hosts

Nov 28, 2011

I purchased this router a few days after its release, and I was very impressed with its functions. I came from a DD-WRT flashed router with all the bells and whistles, and the E4200 lacked some features but I felt it was a fare trade off for the GHz & dual band.All was well with all my settings (quite a few to name QOS,forwarded, etc)I also updated the firmware when it came available and re entered same settings.

 Approx 3 months after use I had 0 WAN connection via eth0 or WIFI, when I logged into router I  was pulling a Public IP from my ISP. I could ping from inside the router but no connection on any hosts, very strange. Powercycling Modem/Router yielded same results.. I then backed up my vast amount of settings, and did a 30/30/30 reset.. With no configs I had no issue browsing on any host on my network. So I restored from backup and the issue was back again..So I did another 30/30/30 reset. Then went and reentered the exact same settings as before and the issue was gone.

Cisco WAN :: 2800 Can't Ping Directly Connected Devices

Mar 28, 2013

I'm trying to configure a 2800 series router. .I'm consoled in and put a basic config on the router (see attached). After putting this basic config on, I plugged it into a small unmanaged switch, changed my laptop's IP and plugged it in the switch also. I can't ping the router from the laptop and vice versa. This is the second switch I've tried this with, so it must be.The first switch, I installed at location, connected a cisco cable to it and a local server, so i could remote in and finish configuration. In that scenario, I had plugged the switch into a managed switch and had the same result as I'm getting now--can't ping IP addresses (can't ping the switch's IP, not can it ping local IPs).

Cisco Switching/Routing :: 1841 - Unable To Ping Remote Gateway Or Hosts On Other Side Of Router

May 30, 2012

I am just setting up a simple scenario with a 1841. Server @ 172.31.1.1 cannot ping 172.31.0.254 or 172.31.0.105. It can ping 172.31.1.250. The router can, on the other hand, ping devices on both networks. This is just for testing routing theory so I don't know why hosts on either side of the network cannot ping each other.
 
I am only using the FastEthernet interfaces on Router 1841.

Cisco Firewall :: 2800 Routers / ASA 5510 Cannot Ping Via Route Inside?

Mar 3, 2013

I recently added a business cable modem to relieve some of the congestion I was getting on my T1 for our MPLS network.  There was an ASA 5510 collecting dust in a closet here and I thought it would be the perfect device for firewalling the traffic coming in from the Cable modem, and handling the routing of our internal MPLS traffic as well.  Internet setup was cake.  The test laptop I have using the ASA as it's gateway has great internet service but it cannot ping across either of our MPLS networks.  I have one MPLS with AT&T and one MPLS with EarthLink.  My hope was to use the cable modem as the Default route for all unspecified internet traffic and route our internal MPLS traffic to the cisco 2800 routers that are currently in place for the MPLS.  I can ping across the MPLS when I telnet to the ASA, but I cannot ping across the MPLS from the client that is connected to the ASA.
 
Here's the topology I'm working with

Cisco Firewall :: ASA 5550 - Cannot Ping SITE 1 PIX From Internal IP

Oct 15, 2012

We have two networks HQ and Site1 and for some reason we can’t ping the inside IP for Site1 PIX device. We have site-site-VPN set up between the two and everything works fine except we can’t ping the Site1 PIX from internal IP. However, I can ASDM/SSH in from HQ to the external IP of the Site1 PIX. 

HQ is using an ASA 5550 (172.1.0.1) PC from HQ (172.1.64.x) Site1 is using a PIX-515E (172.2.0.1) PC from Site1 (172.2.64.x)
Ping from HQ PC to Site1 PC (172.1.64.x to 172.2.64.x) works fine
Ping from Site1 PC to HQ PC (172.2.64.x to 172.1.64.x) works fine
[code]... 

ASDM/SSH from any HQ PC to Site1 PIX internal IP (172.1.64.x to 172.2.0.1) doesn’t work
ASDM/SSH from any HQ PC to Site1 PIX external IP (172.1.64.x to Site1 external IP) works fine
 
Everything was working fine until we recently changed the outside IP address for Site1 because we switch to a different ISP. Nothing changed on the HQ ASA or Site1 PIX other than the outside IP address on Site1 PIX. I did rebuild the site-to-site VPN tunnel between Site1 and HQ.

Cisco Switching/Routing :: 2621 - Unable To Ping Internal Interface

Dec 3, 2011

I've got a 2621 configured as my main gateway to the internet - right now it's obtaining a DHCP ip from a the ISP's proprietary router set to bridged mode.
 
As of now, I'm unable to ping the internal interface of the router.  I can ping external IP's only, even though I have DNS servers listed, i am unable to resolve host names.  I'm running a few servers to which people are able to connect to my web server, among other services.  I even have a crypto map setup to another 2621 across the country and can ping all internal ips on the other end... I JUST CANNOT PING THE INTERNAL INTERFACE of the router!!

I've noticed that when I ping the router during it's boot process (using linux un-interupted) I get a response in a very short window, then dies again.  I'll post my config below:
