Cisco Firewall :: 5510 - Get Internet Connectivity On ASA Inside Interfaces?
Dec 30, 2012
I have a Cisco ASA 5510 with 3 inside interfaces each connected to a 3750X switch port in a vlan. Outside interface is connected to external router with 209.155.x.x public IP. Static route exists for outbound traffic on outside interface.
3750X is configured for inter-vlan routing. VLANs 10, 20, and 30 have 172.16.x.1 IP address with static routes pointing to the each of the ASA inside interfaces - 172.16.x.254. Connected hosts are configured with gateways pointing to the appropriate vlan interface IP - 172.16.x.1.
Inter-vlan routing appears to be working - I can ping back and forth between hosts on different vlans, and I can ping each vlan IP.I can also ping each ASA inside interface from a host in the appropriate vlan, but I cannot ping internet sites (4.2.2.2 or 8.8.8.8) from hosts on the inside interfaces.
I can ping 4.2.2.2 from the ASA CLI. I can ping internal hosts on vlans 10,20,30 from the ASA CLI. But, no luck with pinging from inside host to internet hosts
I have now configured another inside interface (ethernet0/2) on ASA with the IP 172.16.0.254 and I have connected it directly to another switch with a management IP 172.16.0.5.
The problem is that the two inside interfaces (130.130.0.254 &172.16.0.254) cannot communicate with each other thus the e0/2 172.16.0.254 interface cannot access the internet.
I have two inside interfaces (both security level 100) inside and inside110. Inside is 192.168.105.3/24 and inside110 is 192.168.110.3/24. I have a PC on the 192.168.105.0/24 network. I cannot ping the 192.168.110.3 IP of interface inside110.
I need to route to sub nets form 2 different ASA interfaces. The ASA also has an outside interface works like gateway for internet access. Here is my configuration:
ASA Version 8.2(1) host name ICE3 names interface Ethernet0/0 name if outside security-level 0 ip address 201.199.xxx.xx 255.255.255.248 [Code]....
so i have a ASA 5510. The ASA is Connect with the Internet through PPOE DSL MODEM
The outside Interface get an IP. The Inside Interface get through DHCP from the ASA the Internet DNS SERVER (T-Online) But the HOST do not connect to the Internet because the DNS Server is timed out
I have an ASA 5510 which i've configured for internet access.I can connect to the internet from the ASA box,I can ping public networks from the console of the ASA box,but cannot access public hosts from internal hosts connecting via the ASA box.Find my config below to know what i ahave omitted or committed.
I trying to allow traffic between 2 inside interfaces with the same security level. VLAN1 and VLAN15. The are on different physical ports on the ASA. I tried to configure this through the GUI Web interface and checked ' enable traffic between two or more interfaces with the same security levels'. With this ASA version, I do not need NAT to allow this, correct?
Inside is connected to my internal network, inside 2 is connected to the network of a sister organization, outside is outside.
I'd like to be able to route between from inside to inside 2, and have NAT translate me to inside2's address.
I have inter-interface traffic configured, and when I use a NAT exemption, I can route fine. But the resources on network 2 must see my request as coming from the inside2 interface IP.
I've been trying to figure this one out for quite a while. I currently have 2 inside interfaces (data, phone) and I am moving to 3 inside interfaces (servers, workstations, phones). I have not been able to get any traffic between the interfaces. With the current setup it was not a major problem. With the new setup it will be a major problem.
Today I run into a problem with enabling ICMP traffice between two inside interfaces on ASA5510 (version 8.2). I tried to ping from 192.168.1.2 to 192.168.2.2 Failed. But I can visit outside websites or ping from any of the two addresses above to 8.8.8.8 So I checked the configuration shown as follow
I have deployed a read only domain controller in our DMZ as part of a domain-related project. That machine needs to be able to reach domain controllers on our internal network. To do so, it should traverse our ASA 5510, going from the DMZ Interface (security level set to 60) to the Inside Interface (security level set to 99).
I've created an ACL as following (alerting hostnames in the example):
access-list dmz_access_in extended permit ip host dmz.rodc.domain.local object-group int-domain-controllers
I've read in various spots that you have to create a NAT when traversing security levels, going from a less trusted interface (DMZ) to a more trusted one (internal.) Since this link will carry domain traffic, we do not want to create a real translation. Thus, I created a stand-in NAT that points to its own IP as follows:
Long story short, the connection fails. I'm able to access other hosts in the DMZ and on another interface configured with the same security level (which I've explicitly allowed), but trying to go from the less-trusted DMZ to the more-trusted internal fails.
I have ASA5510 with PLUSE License.I have 2 Inside interfaces as STAFF and MAIL and two Outside interface OUT_STAFF and OUT_MAIL which is in separate ISP's.now i want to nat STAFF to OUT_STAFF and MAIL to OUT_MAILbecause I'm having two default routes it gets impossible to do.
I've been following most of the comments in regarding how to allow communication between two internal networks on a ASA5510 8.2.5 But I am still a little confused about to how to set my firewall. I made chages to it and still do not have the desired results.
I need to allow comunication between Interface 0/1 and Interface 0/2. See configuration file with fake or dummy ip address below.
ASA Version 8.2(5) ! hostname ciscoasa domain-name lxx.com
I have a question regarding firewall configurations. Is it possible to have two interfaces ( for two internet service providers) one for voice and one for data. Can I have two Outside Interfaces that one will apply to a pppoe client group and the other will apply to a static IP? Is this possible and if so What would be the steps on applying this connection? Also to note I have a point to point connection already established for the pppoe. I also have another point to point connection for data, but however I do not know how to apply this to the firewall.
One Host on inside network needs to access customized application hosted on Internet. Its a customized application run on port 80, 443, 5000-to-50020
How do I allow this host access for this specific application. I got ASA 5510 and host is in the inside network, we also got an ACL on inside interface to have control.
-Host IP on inside network - 172.16.30.15 -Application to access - 74.219.x.x -Inside ACL name - inside-acl
I am trying to setup intervlan routing with a Cisco ASA 5510 and two 2960-S switches. The 5510 currently is using ASA Version 7.0(2) and has a base license. I tried to create a sub interface today based on some info I found regarding the routing piece and it didn't recognize the command. I'm thinking I may need to update the IOS code or the license on the firewall. I know the syntax was correct because I looked it up and found it in a Cisco document.
we have two ASA 5510 connected in failover, and a pair of cisco 2960s switch connected in stack. Currently one interface of primary ASA is terminated on switch1 and a interface from standby is connected to switch2 as Inside, and switch1 and switch2 are in stack. for redundancy purpose i want to use multiple interfaces of ASA for inside , so first i thought to use etherchannel , but it has a limitation that , it cannot be terminated on stack switch(as per cisco document [URL]
So my question is :
1. can we use redundant interface feature where 2 physical interfaces combined to a redundant interface (eg interface redundant 1) for inside redundancy purpose.
2. Can these ports from primary/standby ASA terminated on stack switches (2960s), will this work (if the switch with active port goes down, will the other port take over in the redundant interface with the other switch).
I have a mail archiver (hardware device) in my network that I need to access to from the Ipad/iphone. There is an app for it but I have to allow the access on the ASA. I created an 'object' for the device and added a Static NAT entry for it, then added an access rule. Its not working so I am guessing I did it wrong. The device uses port 8000 which I also added to the object. correct commands, or using the ASDM works too.
I ran into a very strange icmp ping issue. The network has been working fine other than the issue listed below, L2L VPN works fine and all three data centers can access each other via L2L VPN.I have three ASA5510. [code]
I build a Config with a DMZ,INSIDE and OUTSIDE Interface. My Plan is to use the IP-Address of the OUTSIDE Interface with PORT to setup a HTTP Server In the DMZ
But my Config doesn't work. And I have no Plan why .....
The Inside Interface have to work normal. The Traffic to the Internet is TRiggert from Inside with Dynamic PAT
ciscoasa(config)# exit ciscoasa# show run : Saved : ASA Version 8.4(1)
I am setting up a new ASA 5510 on our inside network so that we can terminate our VPN connections on this ASA. I can get the VPN to work fine however I noticed that once I turned on my VPN profiles now when I try to access the ASDM I'm getting the VPN logon page. So I decided that in order to resolve this I need a separate interface dedicated to management of my ASA.
I'm trying to come up with the best way to do this. I've got two ports on the ASA plugged into my core switch. One is on a separate VLAN from the rest of my network traffic. This is the port I want to use for management. The second will be used to route all of my VPN traffic.
So far I haven't been able to get this to work at all. My thought was that it had to do with routes, NAT and ACLs. I've been playing with them but can't get any combination to work.
I am configuring a new ASA 5510 to replace a SonicWall and I have a problem with an HTTP Connection inside my LAN.PC from the LAN ( using ASA LAN interface as gateway) can't Connect to a Camera video Web Server (192.168.4.20) on Port 80 whereas I can Ping it.
ADSM logs show :
106015# Deny TCP (no connection) from ip1 to ip2 Flags RST on Interface LAN.The adaptive security appliance discarded a TCP Packet that has no Associated connection in the adaptive security appliance Connection table.
- I Enabled command "same-security-traffic permit intra-interface"
- HTTP inspection is disabled.
I used Capture feature on the Ingress Interface, I joined the Logs and a part of my ASA Running Config.
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.
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 hava ASA5510. INSIDE,DMZ and OUTSIDE interfaces are configured. I hava web server on DMZ ip:10.0.0.1 and it is static natted to 1.1.1.1. From internet i can reach to web server with IP:1.1.1.1 and from INSIDE connect to web server with IP:10.0.0.1. Now i want to connect from INSIDE to WEB server via public IP(1.1.1.1).how can configure it?
This is an issue I'm currently exploring with TAC, but I'd like a quick reality check. We have a pair of ASA 5510s in Active/Standby stateful failover mode. In some tests failing over from the active to the standby system breaks SSH connections from hosts on our Inside to hosts on our DMZs.
A specific example is our backup server on Inside which is connecting to our mail server in the DMZ2, and running ssh/rsync/scp for the backups. A running backup job fails with network timeout errors when I trigger the failover. Also, sometimes the mail server loses or hangs on its connection to our LDAP server in DMZ1, although sometimes this connection is fine (DMZ2 is more "inside" than DMZ1, and I assume the LDAP look ups are many short connections, vs the rsync backup being one long connection).
TAC has suggested that open SSH sesions will always fail when the ASAs failover. I believe this is true for management connections to the ASA, but I don't see why it should be the case for an SSH session through the ASA to a server in the DMZ. TAC has suggested that I open some connections to servers in the DMZ and test what happens, and I can do so this Wednesday morning during a maintenance window.But, in general, is this true? That is, given an SSH session from a workstation to a server, should a failover break it? If so, why?
That is, all our inside VLANs are routed by our core L2/3 switch to a VLAN that connects to the Primary and Secondary ASA's INSIDE ports. There are also seperate VLANS on the core for the ASA's DMZ1 and DMZ2 connections, which go to both ASAs and to any servers in these zones.
The description of the ASA Stateful failover [URL]says: "The state information passed to the standby unit includes these:
· The NAT translation table · The TCP connection states · The UDP connection states · The ARP table · The Layer 2 bridge table (when it runs in the transparent firewall mode) · The HTTP connection states (if HTTP replication is enabled) · The ISAKMP and IPSec SA table · The GTP PDP connection database
[code]....
I'm not quite sure what the ISAKMP and IPSec SA tables do, but shouldn't an SSH connection through the ASA be just a TCP connection? "For us, SSH from Inside to hosts in the DMZ survives failover," or, "Yah, failover breaks all SSH sessions."
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.
