Cisco Firewall :: Failover ASA 5505 - Setup Second Inside Interface On Firewall?

Feb 19, 2012

I have a Cisco ASA 5505 in our office. We are currently using Interface 0 for outside and 1 for inside. We only have 1 Vlan in our environment. We have two three switches behind the firewall. Today the uplink to Interface 1, to the firewall, on the switch went bad. I want to setup a second inside interface on the firewall and configure it as failover incase this happens again. I want to attach it to the other switch. Can I do this? If so, what do I need to do? would it only be a passive/standby interface?

I have a new ASA 5505 and all is working fine, I can CLI and ASDM into it, but just can't ping the inside interface, do I need to enable a feature to make this work somehow?

Cisco Firewall :: 5505 Inside Interface To Another Switch?

Apr 23, 2012

I am connecting the inside interface to an upstream switch and therefore will need to assign a static IP address to the inside address as I did below:
 
#sho int ip brief 
Vlan1                      123.123.123.123  YES manual up                    up
 
I will also use this to manage the ASA. I am having a problem with the network configuration of the inside interface as I can't ping the gateway and/or the in IP of the inside interface.Do I need to add any routes?

Cisco Firewall :: 5505 - Can't Ping ASA Inside Interface

Dec 12, 2011

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.

Cisco Firewall :: ASA 5505 Dropping UDP / 53 Traffic On Inside Interface?

Jul 21, 2012

We have a Cisco ASA 5505 (v7.2(3)) with a "fairly" normal configuration yet we have a problem where it appears UDP/53 traffic is denied on our inside network.
 
here is output from our sys log:

SyslogID   Source IP      Dest IP    Description
305006      172.18.22.3                   portmap translation creation failed for udp src inside:172.18.22.156/42013 dst inside:172.18.22.3/53
 
To give some clarification:

172.18.22.3      is one of our DNS servers
172.18.22.156  is a device we're experimenting with.
 
We've bypassed the Cisco by using a 4G wireless router with this same device - and it works flawlessly.Here is a [scrubbed] copy of our config. It is what I inherited from the previous admin - I'm not sure of all its finer points (I'm not Cisco certified -- perhaps I'm just certifiable.)

Cisco Firewall :: ASA 5505 - Dropping TCP Connections On Inside Interface

Feb 12, 2013

Trying to add inside routes on an ASA 5505 to point traffic to another gateway for other connected networks is resulting in the following error 6Sep 16200 819:13:5810601510.184.236.1265003810.170.54.1823389Deny TCP (no connection) from 10.184.236.126/50038 to 10.170.54.182/3389 flags RST on interface insideI believe the problem is due to the Asymetric tcp connection and the ASA is dropping the connection because it only see one half of the traffic.Is there a way we can stop the firewall dropping the TCP connections on the inside interface? i've tried removing the threat managment which didnt work.Annoying thing is were putting the ASA 5505's in to replace old Watchguard soho firewalls only the watchguards forwarded the traffic no problem at all.

Cisco Firewall :: ASA 5505 - Drops Inside Interface On Switch

Apr 6, 2011

I have a pair of 5505's in transparent mode and connected them to C2960S. The inside interface (which is VLAN5 on the switchport) keeps dropping, going in to error state. There is no log reference in the switch and the interface shows as UP. The standby ASA has no problem, both interfaces on the switch is up. As soon as I failover the units over, the active node inside interfaces drops.

Cisco Firewall :: Configure DHCP Server On Inside Interface ASA 5505

May 9, 2012

We've just started with the ASA 5505. We do run a DHCP server on the inside interface, so it is in the same VLAN 1 as all of the clients. However, we cannot get it to work.We can't use DHCP Relay, as the ASA 5505 only allows to relay to DHCP servers in a different subnet.Or do we have to move the DHCP server to a different subnet. If so, how would we configure that scenario?

Cisco Firewall :: Setup ASA 5505 Access Or NAT Rules To Inside Server / IP Cam

Oct 25, 2012

I'm having trouble setting up the correct rules on an ASA 5505 I'm using in my home office.  I have a couple of IP Cams I need to access remotely.
 
I've tried setting up simple NAT(PAT) and/or Access Rules, but it hasn't worked.  I have a single dynamic IP for the Outside interface.  Call it 77.76.88.10 and I am using PAT.  The CAM is setup to connect on port 80, but could be configured if necessary.  I've tried setting up NAT Rules using ASDM as follows:
 
Match Criteria: Original Packet
Source Intf = outside
Dest Intf = inside

[Code]....

I'm afraid to use CLI only because I am not confident I'll know how to remove changes if I make a mistake.

Cisco Firewall :: ASA5505 Can't Ping New Firewall On Inside Interface

Jul 14, 2011

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.

Cisco Firewall :: PIX 501 / Can Traffic Goes From Inside Interface To Outside Interface

I have Pix 501 firewall and I'm just configuring the device for "Email Server" to allowing POP/SMTP.
 
Inside Interface Address: 132.147.162.14/255.255.0.0

I have been working with ASA 5510,20,40,80 but not with 5505 this vlan and its interfaces are quite confusing.Just want to know how it works and its connectivity to Cisco Switch.Do i have to put the interface of the switch in the same vlan as i am creating the interface vlan in firewall ?Now the switch port connecting to this Eth1 interface should also be in the same vlan ? i.e vlan3 ?? or it will be in trunk ? The default configuration shows the eth0 with no access vlan and interface eth1 with access vlan 2... does it mean the eth0 is in vlan1 ? (Nativ Vlan ) ???

Cisco Firewall :: 7.2.3 / Upgrade ASA Over VPN Via Inside Interface?

Jan 17, 2013

I am trying to upgrade a Cisco ASA over an IPSEC VPN tunnel. My FTP server is on the remote side of the VPN tunnel but I am initiating connections from the inside interface of the firewall. I am currently managing the Firewall over the VPN via it's inside interface (using the management-access inside) command. When I try and update via FTP, the connection is going straight out the outside interface (and not across the VPN tunnel) I have tried upgrading via TFTP but it keeps stopping randomly with (unspecified error) I normally upgrade via FTP though but it's not working in this instance. Essentially what I am asking, is is there an equivalent command for FTP that there is for TFTP: tftp-server interface ip anyconnect I need the connections to originate from the inside interface so they traverse the VPN. I am running 7.2.3?

Cisco Firewall :: ASA 5505 VPN Failover Over WAN?

Oct 9, 2011

I have a ASA 5505 which is connected to a remote site which also has a ASA 5505 over a L2L VPN tunel. One of the sites has a WAN failover configured with two ISP which is working successfully.
 
But, when the WAN connection fails over to the backup connection the VPN link breaks as the peer site IP address has changed and the VPN can not establish a connection.
 
Would it be possible to configure a VPN failover so that when the connection failovers so will the VPN tunnel?

There are 2x Cisco ASA 5505 in an active/standby failover config.  The primary asa 5505 has been reset and the secondary is now running as active.  I would like to reintroduce the primary again but need to know how to do this.
 
Ideally I would like to remove the failover config and start from scratch.  Do I just need to enter the following to disable failover on the active secondary box?
 
no failover
no failover lan unit secondary

So we currently have a T1 connection at our location. We were looking to add a high speed cable internet and add an ASA 5505 with Security plus license to do failover between the two. I have found a few examples on how this would work but curious about a couple things.
 
We would want the Cable to be the primary, T1 as a backup.Currently the IAD that handles our T1 does dhcp, dns, and NAT.. Who/what would handle these items with the setup above?

Cisco Firewall :: ASA 5550 Inside Interface Hangs

the inside interface on our primary ASA seemed to "hang". It dropped all the packets it received. Because the interface didnt go down, failover didn't happen. Device's info;

Cisco Firewall :: Cannot Ssh Or Ping ASA 5510 From Inside Interface

Apr 4, 2012

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)

Cisco Firewall :: Slow Access Or NAT To Inside Interface On ASA 9.1

May 13, 2013

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.

Cisco Firewall :: ASA 5510 Inside Access To NAT IP On Outside Interface

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

Cisco Firewall :: ASA 5540 Redundant Interface Failover

May 8, 2011

I have two ASA 5540s, ver 8.4 configured in Active/Standby failover.I am also using the redundant interface feature for my Inside interface.  Gig0/0 is the active primary and Gig0/1 is standby.
 
I will activate failover monitoring of the Inside interface using the monitor inside command.
 
My question concerns the failover monitoring of the redundant interface.  If the gig0/0 connection were to fail would the Gig0/1 interface become Active, AND simultaneously result in a full device failover?
 
Or, does Gig0/1 of the Inside interface redundant pair simply become active and not change the Inside interface device failover state?  Thus NOT resulting in a device failover.
