Cisco Firewall :: ASA 5510 - Users Unable To Access Internet Through Firewall
Feb 26, 2013
I have some problem with the ASA 5510 ver 7.0(6). My manager wants to keep this as backup. tried lots of things but still users not able to access internet nor can i ping anywhere.For example when i ping 220.127.116.11 i dont get any reply.The runing config is below for ur ref :
I have a normal setup of ASA5505 (without security license) connected behind an internet router. From the ASA5505 console I can ping the Internet. However, users behind the Firewall on the internal LAN, cannot ping the Internet even though NATing is configured. The users can ping the Inside interface of the Firewall so there is no internal reachability problem. In addition, I noticed that the NAT inside access list is not having any hit counts at all when users are trying to reach the internet.
When i replace the ASA5505 with a router with NAT overload configuration on it, the setup works normally and users are able to browse the internet.
The ASA5505 configuration is shown below.
interface Ethernet0/0 description Connected To Internet Router switchport access vlan 10
I am migrating over from and old PIX to an ASA 5510. After configuring the new device everything else is functional (Internet) but users are unable to pass traffic when connected through the vpn, they are able to authenticate and I see their session connected on the ASDM but no data is passed..[code]
I have a issue that i am at a loss as how to solve it. I have an ASA 5505 as my firewall. I have users from other companies who visit from time to time and are unable to use their outlook email to send messages. They can however receive messages without a problem. I also have a situation where users who use windows live to access gmail are unable to send messages.
I have narrowed it down to the fact that these uses are using ssl/tls to send the mails. I did some research and found out about the inspect esmtp setting in the ASA. I have disabled it and i still have to problem. I have also removed all outbound deny statements and still no luck.
Of note is that i can send emails without attachments. They take a long time to go out ( from minutes to hours) but eventually they do. Emails with attachments of even 10k do not go at all.
I was running image 8.2.3 and i downgraded to 8.0.5...still did not work...i upgraded to 8.4.3...still did not work. I am now back at 8.2.3.
My Firewall config is attached. I am at my wits end as to what else to try. The company has not renewed support for the device so i am on my own here!
I have recently deployed a Cisco ASA 5510 Security plus firewall on my companies network, but there is a problem that I am finding hard to get by and I think it is ASA related.
From (inside we are not able to hit any of our sites that are on the (outside). I have nat policies in place to translate the public to private, but I think I that I need some thing more. This seems to be occuring mainly with our external web sites as well as another animoly with regards to FTP (but it may be fixed if the http issue is resolved.)
I was hoping some with a lot more knowledge on ASA firewalls than my self can spot the error in my run-cfgs.
i am unable to launch ASDM, and access https:// to run Asdm..everything worked find yesterday but now for some reason it wont work?When i am trying to log in with the asdm it just hangs on the connecting to device... please wait...When i am tryng access the https://... i get the ssl do you want to trust.. and i press proceed anyway and i get an error
Asa 5510 Device manager version 6.1 System image file is "disk0:/asa804-k8.bin
Also i am accessing the asa with ssh without any issues
I have a weird problem which I have already submitted a TAC ticket about. When users authenticate through AnyConnect into our HQ ASA 5510 they grab an address from 172.16.254.x. What we have been noticing intermittently is that when logged into our network through the client they are unable to access their resources at one of our remote offices which is connected over l2l to the HQ ASA. This problem just started randomly a week ago and we have been working with Cisco trying to create a solution.
My quick fix is logging into a device at the remote office which is trying to be accessed and pinging the gateway of the virtual subnet for AnyConnect users. When I ping 172.16.254.1 it goes through after a few dropped icmp packets and then the issue is resolved for about 8 hours or so.
I am using two firewalls to connect two different offices. Firewall 5510 is running ASDM 6.3 and 5505 is running ASDM 6.2, Problem is that even after connecting two sites, i am unable to ping remote network from either side. I am mentioned static route as tunneled.
I am unable to see 4th interface on my firewall i.e fastether0/3 on my firewall ASA 5510.
Below is the output. ciscoasa# sh int ip br Interface IP-Address OK?

I Have an asa 5510 running code 7.2 configured with ssl vpn,ssl vpn users able to connect to to portal which i have configured with the required resources,but the thing is that these ssl users unable to upload files to cifs shared directory , although they have full access to the shared folder
I can get access to the internet from the ASA 5510 itself and that is confirmed via pings. However, anything behind the ASA does not have internet access, on any VLAN/sub-interface. I've attached my running-config.
the set-up is: a DSL modem in half bridge (it does all the PPPoE connection) passes our static IP (55.167.x.x) to the ASA's outside interface ... (the modem has an IP of 192.168.1.1, but not sure this matters)
then I have one inside interface on 192.168.43.1, which connects to a server and we have a working site-to-site VPN between this server and a client.. so I know most of it's set up right ... nothing else is on the 192.168.43.0/24 network.
the management interface is on 18.104.22.168/24 so it's out of the way and incidentally connected to a dedicated PC, which also has console access via the blue serial cable.
the last interface Main_Network is on the 192.168.0.0/24 network and it's this that I'm trying to get to work... at the moment I just have one Windows PC connected directly (does it need to go through a switch?) into the ASA for testing with a static IP (192.168.0.72), but I can't ping anything outside from the PC... only the ASA's interface (at 192.168.0.30).. I have the gateway on the PC set as 192.168.0.30 by the way.
The ASA can ping all the inside machines and anything I like outside.
Here's my config ... the static routes are there for when this replaces the current modem/router and the whole network plugs into the ASA.
ciscoasa(config)# show running-config : Saved : ASA Version 8.2(5) ! hostname ciscoasa
We have a ASA 5510 which was running 8.0.2, we recently upgraded it to 8.2.5 and since the upgrade remote users for exchange 2007 are not able to download any large email attachments(over or close to 1MB). This is only happening to Outlook anywhere users or OWA users who are connecting to the exchange server using https(443) externally. If the same users connects internally they do not face any issue. When i check the logs on ASA i am gettings lots of RESET-O and RESET-I entries. Looks like the connection between the client and the server gets reset.
I have an ASA 5510. I am doing a new install at our new data center. I am having trouble getting internet access from an inside LAN interface to the outside WAN interface.Our colo center has given us the below IP info. [code]If I do a static config on my laptop of IP 198.145.XXX.82 Mask 255. 255. 255. 240 DG 198.145.XXX.81 I am able to get the web fine from the line in our rack. I used the ASDM software to setup the ASA. I set its WAN IP of 198. 145. XX X. 82 and mask as 255.255.255.40 for interface 0/0. For interface 0/1 I made a management LAN of 192.168.180.1 with mask of 255.255.255.0.I can connect to my LAN ok but do not have outside internet access. I have also tried .80 and .81 for the WAN IP of the ASA. [code]
I have to configure a default-factory firewall (ASA 5510) in a simple scenário like this image represents:At this moment i have configured the interfaces as represented above and at this moment what i want is grant access from a LAN computer (10.10.0.0/24) to the internet.
Should i configure some acl? I read that all traffic from an interface with a superior security level to other interface is allowed, so since my inside interface has a security level of 100 and the outside 0, it should be possible access to internet from an inside computer?!
From all configurations and examples i have seen around, they all contemplate a fixed IP address from the ISP, but in my scenário i have a dynamic one. This fact matter for the configuration i want to do?
My firewall is running the software version 8.2(5).
We need to deploy a Cisco ASA 5510 behind the Internet facing router for Remote Access VPN (RAVPN). We bought the block of 16 IPs (in a different subnet) which is routed through the main router (69.x.x.x)and configured the outside interface of ASA with a public IP 64.x.x.x and subnet mask 255.255.255.240. Below is the network structure.
I have a subnet for guest network access, both wired and wireless. We have a Netgear ProSafe that is trunked to a Cisco 2901 performing 'Router-on-a-Stick'. For most internal traffic, it all stays behind the ASA. But for guest traffic, I have a route-map that sets the next-hop address as the outside interface of the ASA. The question is, how can I still permit those users to access our internal DNS servers? Do I need any particular NAT translations, exemptions, DNS doctoring, hairpinning, etc.? I have an ACL on the inside interface that permits traffic from the guest networks to our internal DNS servers, and then the next ACL line denies any other traffic from the guest networks to any of our internal networks.
I have installed a new ASA5510 with CSC, and everything is working properly except the access to websites using https. All sites/access to them seem to be blocked by the ASA. I have read that this access is by default enabled and I have tried to add configuration to allow https access to the firewall but without success. [code]
I have a remote VPN with split tunnelling enabled. Currently, users connected to this VPN browses internet with his/her internet connection. Now, my requirement is that a roaming user connecting to the vpn must use our company's internet connection for his browsing purposes. How can I do this?Equipment we are using: ASA 5510
I've been struggling with gaining access to the inter through our Comcast business gateway. We have had Comcast configure the device fro true static IP subnetting. Turned of local DHCP on the device etc. Here is my config.
This is my first time to use the Cisco ASA 5500 family. I have a request from a user to create an access rule, to allow all LAN traffic to Destination IP address 22.214.171.124, 126.96.36.199 with Destination TCP port 5060,5061,5070 and UDP port 50000-52399.
I have recently setup Splunk to receive my syslog messages from my ASA 5510. In the past I used kiwi without observing this issue, but I needed more features than kiwi had available. Anyway, anytime I stop the splunk service my asa does not allow any outbound connections to be established.
Internet ISP -> Juniper SRX 210 Ge-0/0/0 Juniper fe0/0/2 -> Cisco ASA 5505 Cisco ASA 5505 - >Inernal LAN switch.
1. Internet is connected to Juniper Ge0/0/0 via /30 IP.
2. Juniper fe0/0/2 port is configured as inet port and configured the Internal public LAN pool provided by the ISP. And this port is directly connected to Cisco ASA 5505 E0/0. Its a /28 pool IP address. This interface is configured as outside and security level set to 0.
From Juniper SRX, am able to ping public Internet IPs (188.8.131.52).
1. From ASA am unable to ping public ip configured on Juniper G0/0/0 port.(/30) 2. From ASA no other Public internet IP is pinging.
Troubleshooting Done so far.
1, Configured icmp inspection on ASA. 2. Used the packet tracer in ASA, it shows the packet is flowing outside without a drop. 3. Allowed all services in untrust zone in bound traffic in Juniper SRX. 4. Viewed the logs when I was trying the ping 184.108.40.206 in ASA. It says "Tear down ICMP connection for faddrr **** gaddr **
I just configure an ASA 5520, here is the config (the ip address of outside network if going to change from private direccion by reason security).
The problem that I have is the users can access to the web site through the public´s ip address but they do not can access through by name. We review all the config on the server DNS and with the command NSLOOKUP we can see that work fine. The client think that the asa is blocked the connnection.
