Cisco Firewall :: 5505 PAT Between 2 Networks On Same Interface
Nov 6, 2011
I'm using asa 5505 with 8.4(2) and have the following problem.I have 2 Networks. each Network has it's own externel Internet-Ip and also Mail-Server.
[code]
Now I want a communication between the two Mailservers with their external Ip-Address.I did a static NAT from ipnt any to int any or also from int routed to int routed, but nothing worked.Packet tracer showed at NAT-Lookup where the externel adress of the second Mailserver is passed: Info Static translate Network1 to Network1
But it should show a translation from network1 to network1-external.Due to Security reasons, I cannot paste the whole config.Under 8.0 I did the same configuration with Policy-Nat and it worked.

I would like to configure a Cisco ASA 5505 with Dual ISP (ISP 1 and ISP2) and two networks (network 1 and network 2). My customer need that clients in the network 1 connect to Internet with ISP1 and clients in the network 2 connect with ISP2. If a failure occurs in ISP1 (just an example) the network 1 clients connect with ISP2.

1. I currently have a Comcast Business Class Gateway, Cisco 2100 Series WLAN Controller and a Cisco ASA 5505 all connected together to supply LAN and WLAN internet connections on my network.
2. I also have a Card Access Security System on it owns network. It currently does not have internet access.
I would like to put my security system on the internet so that I can support it remotely. To do this, it has to be on a firewalled internet connection.Can I put the two networks on my ASA 5505 and keep them seperate? I don't want to provide a path into the Security System through my current LAN & WLAN. But I do need a frewalled internet connection on my Security System. I am trying to avoid purchasing a seperate firewall.

I have 3 networks coming on DMZ (VPN) interface. Only one network is able to ping the DMZ interface. See below networks coming i on the DMZ.
10.132.24.0/2410.132.25.0/2410.132.26.0/24 Only the 10.132.26.0/24 netork works as it is in the same range as the DMZ interface.
allowing the other two networks to communicate. I've attched the diagram and configs for your perusal.

I have an ASA 5505 with Security Bundle license.
I am able to create 2 LAN networks (192.168.9.0 and 172.16.9.0) Vlan1 and Vlan12 respectively. I also setup 2 outside interfaces (outside1 and outside2).
Network 1 (192.168.9.0 - VLAN1) has no issues going out via Outside1, however I can't get Network 2 (172.16.9.0 - VLAN 12) to go thru outside2.
I put in a static route (route outside 172.16.9.0 255.255.255.0 x.x.x.x), the x.x.x.x is the default gateway of my ISP.

I am new to Cisco ASA and have been configuring my new firewall but one thing have been bothering. I cannot get internal networks and routing between them to work as I would like to. Goal is to set four networks and control access with ACL:s between those.
1. Outside
2. DMZ
3. ServerNet1
4. Inside
ASA version is 9.1 and i have been reading on two different ways on handling IP routing with this. NAT Exempt and not configuring NAT at all and letting normal IP routing to handle internal networks. No matter how I configure, with or without NAT I cannot get access from inside network to DMZ or from ServerNet1 to DMZ. Strange thing is that I can access services from DMZ to Inside and ServerNet1 if access list allows it. For instance DNS server is on Inside network and DMZ works great using it. [code]

We recently changed locations and acquired a new circuit from our provider. They also connected our remote branch office to our main office through MPLS. Now, as I understand it, the branch office basically connects back to the main office through our providers network (MPLS). We have a new router at the branch office which has a gateway of 192.168.1.225. The clients in that office have IP's of 192.168.1.96 - 100, using the gateway of 192.168.1.225.
The main office network is 192.168.0.0 (Gateway of 192.168.0.1)
At this end (Main office), I also have a new Cisco 2900 provided by the ISP, with port 0/0 for the outside connection (connected to the 0 port on my ASA 5505). The ASA's port 1 obviously running into my network hub. The provider tells me that port 0/1 on the 2900 is or should be used to connect the branch office back to here and has an IP of 192.168.0.225, as that's how the provider provisioned it. So, I plug that into the ASA's Ethernet port 0/2. And I'm assuming they have a route setup either on the 2900 or the router in the branch office so that 192.168.1.225 can reach me here at 192.168.0.0.
There is already a static route setup on the ASA: (192.168.1.0 255.255.255.255 192.168.0.225 1). As soon as I plug in the cable, the IP phones at the branch office work, but they can't access the internet or any resources in the main office. My questions are:
1. Shouldn't I be able to just go straight from the 0/1 port on the Cisco 2900 to my hub. At first I was plugging right into the ASA, but I don't think I need to do that, why go from the branch office through my ASA to access resources and then back out the ASA for internet. If they're already coming from 192.168.1.225, through the MPLS network, then they should go right to my network and then back out the ASA.
2. They have to route through the ASA first, in which case, do I need to setup another VLAN for that branch network in conjunction with a static route? I can ping the router and hosts in the branch office through the ASA only!
Below is the running sanitized config:

I'm usually not working with this product, but this is what I'm trying to do.I have 2 internal networks setup on our Cisco ASA 5505 firewall. (not done by me, I'm a new to this product)I'm trying to access a server on one network from a PC located on the other internal network. (preferable through the web gui)When I try "Packet Tracer" from interface "Trust4" it fails on the NAT phase.(Source ip: 10.0.4.99, Destination ip: 10.0.6.99)
When I check the NAT rule, it says:
Type Source Interface AddressDynamic any outside outside.

I just installed a new ASA 5505 for an office with three internal subnets. The three networks can each get online fine and ping eachother, but cannot browse to shares on the two internal networks other than their own. How do I configure the ASA to allow all traffic between these three inside networks?
192.168.152.0
192.168.152.0
192.168.154.0

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 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 ) ???

I setup a site-to-site VPN tunnel at the remote ASA5505. I am able to asdm to the outside interface but not ssh. I switch to telnet and still not allow me to access. I added an ACL to allow telnet any to the outside interface but still not working. In ASDM I see the log Here is the second issue. When I want to change the telnet back to ssh using ASDM I got the following error.

I have a problem where my outside interface stops passing traffic and the only way to resolve the issue is to reload the ASA, the interface never is down it just stops passing traffic. The inside interface never stops allowing traffic to pass as I can get to all my internal servers and shared drives.
The firmware is:

I have setup ASA 5505 with 2 ISP, named outside (primary) and backup, the scenario is if outside down, then backup will take over, it works now. But it is not working when the primary connection cannot reach the gateway with the interface still up.
Is it possible when the primary connection cannot reach the gateway then backup automatically take over?
My configuration is:
ASA Version 8.2(1)

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?

I was asked to block pings from the internet to the outside interface of our ASA-5505 firewall. I found a post that said to enter "icmp deny any outside", however that does not do it.
I created an ACL to try and do the trick, also to no avail:
access-list outside_in extended permit icmp any any echo-reply
access-list outside_in in interface outside
access-group outside_in in interface outside

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.

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.)

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.

If I am using an ASA5505, and I have a configuration similar to below, I see that the untrusted interface is only allowed to ftp to 192.168.1.5. Since the trusted interface is not limited to ftp only can it basically run any protocol it wants to 10.20.30.2, or does it get limited to only ftp by the other ACL on returning packets.Also, is the ACL applied to the interface because the ACL's name is the name of the interface?

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.

I have a ASA 5505 with the security plus license. I have 7 vlans, 2 are guest vlans for wireless and wired connections. I am allowing traffic from the guest vlans to any with the http & https protocols I have ACL's in place before the allow all rule that do not allowed traffic from the guest vlans to the other vlans. Is there any way to have all traffic from the guest vlans to always go to the outside interface for the http & https traffic in stead of trying to go to the other vlans first, I know I have the ACL's in place to prevent the traffic but if I would feel better if I had this in place as well.

I am used to setting up access-lists on outside interfaces with ip addresses that are static. I have recently been given a site that is using a dyndns.org client for name to ip address resolution on an outside interface that is dhcp assigned. I created an access-list to open up ports 41794 and 41795 to an engineering application but everytime I try to connect from the outside I get a syn timeout. The application works when inside the lan. Basically I want to allow outside connections from anywhere on the outside to go to ports 41794 and 41795. I am running a Cisco ASA 5505 on version 7.2(4) Below is my conifg. what I may have misconfigured?
