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.)
ASA Version 7.2(3)
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.
My question is can my traffic goes from inside interface to outside interface? (because the inside interface address not from 10.0/172./192.168 private address)Also I'm allowing internet from this email server (22.214.171.124) so what my access list to be configured? and what my subnet mask shoud be there?
Pix(config)#access-list outbound permit tcp 126.96.36.199 255.255.0.0 any eq 80 Pix(config)#access-list outbound permit udp 188.8.131.52 255.255.0.0 any eq 53 Pix(config)#access-group outbound in interface inside
I need to configure a Cisco ASA5510.Connencted the a single interface I have a switch. To this switch (same VLAN) there are connected:
1. The Subnet of the main office (192.168.1.253)
2. A router (IP 192.168.1.254) that routes the traffic to a remote location (Subnet 192.168.8.0/24)
I have so allowed any traffic incoming to the inside interface as follows:access-list inside_access_in extended permit ip any any and I have permitted traffic intra interface as follows: same-security-traffic permit intra-interface. [code]Unfortunately I cannot RDP into that server. When I simulate the connection via Packet tracer, it tells me that the implicit deny on the bottom of the connections from "inside" (firewall) does not allow the connection. It sounds to me like that "same-security-traffic permit intra-interface" does work only if there are 2 interfaces and not a single one.Unfortunately I cannot just unplug the cable and connect it into another port as the ip is on the same subnet and I cannot configure the other end router.
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?
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 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 184.108.40.206 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 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.
Previous attempts to set up these NAT rules has been met with minimal success. We have been able to get the NAT rules created, and able to ping our inside servers and receivers from a different outside network, but every time we get that far our internal network crashes. Running the Packet Trace utility via the ASDM shows that internal traffic from the servers to the workstations is being blocked by the default implicit rule under the access rule heading that states "any to any, service being ip, action= deny". Reverse traffic from the workstations to the servers is being allowed though. In an effort to start over again, the Cisco ASA has been Factory Defaulted via the CLI, and has had it's Inside network, and Outside IP address set back up. DHCP pool has been setup for a minimal amount of addresses on the inside network, since most of our equipment will always be assigned statics. We reset our static NAT policies, and seem to be having the same problem. My partner and I have been working on this for some time now, and have ourselves so frustrated that I know we are missing something simple. [code]
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've an ASA 5505 connecting to a vdsl modem. The ASA is doing the PPPoE encapsulation. I've noticed the traffic amount on the outside interface is always twice the bandwidth it receives on its inside interface. I can't believe the PPP encapsulation is taking that much. Only two interfaces (inside and outside)
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?
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 have a Cisco ASA 5505 and I have my internal and external interfaces configured but I currently cannot ping from the inside to an IP Address on the outside. I had this setup and working and I have another set of equirement that I am replacing that is working with my service provider so I know it is a configuration issue. When I ping 220.127.116.11 for example I get:
Destination host unreachable
Do I need to add a static route from my inside interface to my outside interfaces?
I have an ASA 5505 with the base license,When I setup the DMZ interface I had to add the deny access to the inside VLAN. The DMZ works fine with WiFi on it, but user's iPhones can't get email unless they turn WiFi off.Is there a simple way to allow HTTPS traffic through the DMZ interface to our internal Exchange server which is NAT'd on the 5505's external IP?
I am testing out some inspection options on an ASA 5505, and I am running into a situation in which applying a http inspection is dropping all outbound http traffic. I get a "protocol violation" error in the logs.
Here is the setup: I'm not sure why the web traffic is getting dropped.
policy-map type inspect dns preset_dns_map parameters message-length maximum client auto
Networking is not my gig, but it has to be at this very moment. We have an ASA 5505. Let me explain what's going on.
On Tuesday I wanted to be able to use the ASDM since there is less room for error. But we only had a console set up. So I ran the following commands...
in ($config) http of course didn't do anything incomplete command http 192.168.1.2 255.255.255.255 didn't anything incomplete command http 192.168.200.254 255.255.255.255 inside
Everything started working after that. Everything worked fine all of wednesday and thursday. Then this morning it stopped processing again. When I traceroute it gets to the machine that is hooked up to the console and stops. So I'm guessing its actually getting to the ASA router and being swallowed up again...
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.
Most examples of NAT translation using an ASA 8.4 are based on servers within a DMZ. In my case it's not because the mailserver also functions as an data and Active Directory server for my local domain. If tried to config the ASA for a while now and throw it in the corner for a couple of months out of frustration. Now I got some time left during christmas break I decided to start again.My purpose is to NAT SMTP / POP traffic from the internet, trough the ASA to my (inside) server. This is what I got so far. With this config I'm unable to telnet the inside server (192.168.1.10) from a remote location.
I can ping 192.168.1.10 from the ASA CLI. I can Ping DNS 18.104.22.168 from the CLI (internet access). I can Telnet the server from the inside LAN, using: telnet 192.168.1.10 25.But I can't Telnet from an outside location using: Telnet 95.*.*.218 25 Because my server is on the Inside interface (diffenrent subnet) do I need an additional route?
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?
I am trying to configure our ASA 5505 so that our users can access our ftp site using [URL] while inside the firewall. Our ftp site is setup so that you can reach it by either browsing to the above url or by browsing to ftp://22.214.171.124 but we are unable to access our ftp site from either route while inside the firewall. We can access our ftp site using the internal ip address of 192.168.1.3.
Here is our current confguration:

Let me start by saying that I'm just starting to study for CCNA, so the ASA seems to be a bit above me yet. The ASA's we are using is for VPN to our corporate office and only allowing access to our Citrix environment, so no direct internet allowed. We have a person who works in the remote office who has need for a caption telephone that requires direct access to the internet. The phone only supports DHCP, and getting the ASA to do an ARP reservations is proving difficult. For now I wrote an access list to allow it's DHCP address out but it still isn't working. The access list I wrote is:
access-list 101 extended permit ip host xxx.xxx.xxx.124 any log access-list 101 extended permit ip any any access-group 101 out interface outside
When I do a show access-list I'm seeing that traffic is hitting the access list as the hit counter has increased. When I do a show conn I'm seeing one of the IP's that the phone should have access to, however the flags are: saA, so I'm assuming they are not getting a response. According to the manufacturer, only outbound connections are needed, no incoming ports required. All traffic is TCP.
Quick question. I have a site - site tunnel that is up and running between a Pix 515E and a 3050 appliance.Tunnel is up and running but on the pix side I dont see traffic from a couple of subnets behind the inside interface.On the vpnallow access list there are no hits So I setup a capture on the inside interface to see if the packets is making it to the inside interface and nothing. There is some traffic making it thru the tunnel that would have to hit the inside int first and even that doesnt showup in the capture.
I am trying to make a basic config on my 5520. The first goal is to make trafic from inside to outside.The internet address is 188.8.131.52 and the default internet gw is 184.108.40.206What am I missing since I can not get trafic from inside to the internet? [code]
I have a Cisco 5512 x Firewall connected with Cisco Layer 3 switch 3750.I have two different WAN connections, one for Data and one for voice. Cisco Layer 3 switch is configured with 2 different VLAN's one for data & other is Voice Vlan. Switch is providing DHCP to computers and IP phones. Voice Pool 192.168.10.0/24 Vlan10 and Data pool 192.168.20.0/24 Vlan20.I need to route my data & voice traffic separately. Cisco ASA is connected with two different ISP's. So, how can I do this configuration so that Voice and Data traffic will route separately.
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]
