We are using several Cisco ASA 5505 with the 8.05 OS on it. The problem is that the SMTP traffic of my ISP(Telenet) isn't passtrough the ASA, I'm using outlook 2010. Before there was also a problem with our local exchange server but I solved this by disabling ESMTP checking in the policies, but it didn't worked for my local ISP.

We have configured ASA 5510. We have configure Ethernet 0/0 ( Outside ) connected with ADSL line and Ethernet 0/1 ( Inside ) Local LAN. we have configured NAT and all the traffic is passing through outside interface. Now we have connected ethernet 0/3 ( leasedline ) interface with static public IP. Now we want to allow SMTP traffic to pass through from this interface.
How to configure it if we want our local lan SMTP traffic sending through new leased line ( Static Public IP ).
I have, what I believe to be, a simple issue - I must be missing something. Site to Site VPN with Cisco ASA's. VPN is up, and remote hosts can ping the inside int of ASA (10.51.253.209). There is a PC (10.51.253.210) plugged into e0/1.
I know the PC is configured correctly with Windows firewall tuned off. The PC cannot get to the ouside world, and the ASA cannot ping 10.51.253.210.
I have seen this before, and I deleted VLAN 1, recreated it, and I could ping the local host without issue. Basically, the VPN is up and running but PC 10.51.253.210 cannot get out

View 2 Replies View RelatedMost 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 4.2.2.2 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'm new to ASA's and PIX units. I've setup a few VPN's now but know next to nothing about logging on these units. I read the config guide for the PIX, but cannot figure out how to get a log of incoming SMTP traffic going on the console.Do I need to use a SYSLOG server? I can probably set one up on my laptop.

I've attached an image of my configuration (ASDM GUI). The part of the image highlighted in green are the SMTP rules. The part highlighted in yellow is another rule that I added about a month ago to block a SYN attack. This rule may be part of the problem because of the order it is in the list. Not sure, though.
I have had two Cisco techs Putty into my ASA to check things out. I think they've done all they can. I wonder at this point if it be wise to just reload the last good running-config I have prior to the Outbound rule being added.
Up until recently one of my sites was able to get to a postilion subnet. Then we started receiving "host unreachable" e-mails. Posting told us SMTP traffic was not getting let in. I've compared the current config to a config that was saved before the issue popped up and found really no noticeable difference.

I am new to the ASA series and I am at a complete loss as to why I cannot configure this router to forward SMTP and RDP traffic to an internal host.
The packet trace tool in ASDM shows complete end-to-end connectivity for RDP but it still fails to connect from outside. This is my config file, what I need to change in order to make it work?
i cannot send emails to outside, i have an access rule on interface inside permit source: inside destination: any servic: tcp/smtp and when i make paket tracer it shows me that the packet is dropped but i cant see through which rule!!

In the settings menu, there is no l2tp in which it was possible to configure a local address of the router. It should be: 10.155.41.41There is an option only for VPN server setup(10.255.255.254), but where it takes a local address that my provder has gave me? - it is not clear. At the same time in the status of the router receives a DNS correctly and the second address embarass me little bet DNS should be:
1) 80.252.130.253
2) 80 252.130.254
first dns is correct, and second one looks like: 80.252.45.86Maybe he does not take a local setting of ip adress via DHCP?

I like the ASA 5505 for SMB and Home Offices very much, but I'm missing sadly a DNS Server or at least the ability of the DHCP Server to use static addresses for certain MAC's. In SOHO's the ASA is the only thing always powerded on and often even a Server where a DNS Server could be installed is missing.So is there a chance to see such a feature (DNS Server and/or static DHCP) in the next SW Release? how name resolution in a small LAN can be done without a local DNS Server?
View 3 Replies View RelatedWe've a Cisco ASA 5505 connected directly to Verizon FiOS Circuit (ONT) box using Ethernet cable. As per the existing documention that I have, the previous configured this as a dedicated router to establish a seperate VPN connection our software provider. They assigned both Public Static and Local Static IP address. When I try to ping the public IP address, it says request time out; so the public IP address is no longer working.
When I ping the local IP address of 192.168.100.11, it responds. The SolarWind tool also shows Always UP signal. How can I login into this router either from remotely or locally to check the configuration, backup and do the fimrware upgrade?
I also tried to connect my laptop directly to the ASA 5505 router LAN port. After 3 minutes, I'm able to connect to Internet without any issues. However I don't know the IP address to use to login.
I'm having trouble setting up local LAN (reach inside network when VPN connected) and Internet access (reach internet when VPN connected) for my VPN CLients when they are connected to my VPN, They can connect, no problem there, but I can't reach any resources when connected. My pings time out, both to my inside network and to public ip adresses, the only thing I'm able to ping is my ASA (172.16.30.1), and I don't se any routes under "Status/Statistics/Route Details" in my cisco VPN Client (when connected).

I wish to restrict this to their IP's only (they have two) and I am unsure on how to do so?

View 14 Replies View RelatedA couple of weeks ago, one of our ASA 5505s failed, and Cisco TAC shipped out a replacement. I was on vacation, and my assistant worked with TAC to get our backed-up configuration restored to the new hardware. This backup was just a copy & paste of the "show start," rather than an export done from ASDM. Anyway, since I got back on vacation I was able to iron out all the wrinkles from the configuration restore, except one. The remote access VPN isn't quite working. This VPN is only used in emergencies, when I can't access that branch office's network via our WAN.
What's happening is that clients are getting "authentication failed" messages when connecting. On Windows, it's an error 691. The VPN is set to authentication against RADIUS (Microsoft IAS server). The IAS server reports that the connection and authentication is successful. AAA RADIUS authentication tests on the ASA succeed, as do authentication & authorization LDAP tests. Basically, everything was working fine before we swapped in the new hardware, and I've gone over the configuration with a fine-toothed comb to ensure nothing's changed -- but clearly, I'm missing something. The new ASA is otherwise operating perfectly.
I have asa 5505 with security plus license, I configured dual ISP with two different ISP provider. I followed below cisco document to configure dual ISP [URL] The Configuration works during the testing, while removing the primary ISP cable from firewall. The problem i am facing is my primary ISP is down but the gateway is still up and it not switch over to backup ISP. For SLA which IP should i monitor so once my primary ISP is down it will fallback to Secondary.

This is my first post in CSC. I have two issues with ASA 5505. I have configured ASA to use Easy vpn (ASA as RA server). Users are able to connect to vpn with out any issue and there is no diconnections with VPN. But when the users are trying to RDP to server it connects and disconnect as soon as login. some time it connect for 2 mins then it fades out for some time then it reconnects again. I guess I have give correct access-lists. Please find the Running configuration in the below.

I ran into a very interesting problem that occurred today and I'm trying to figure out why it happened. If it was one ASA 5505 that just required the reboot, then I'd have just chalked it up to a glitch, but when we built a new AD/ DNS server on the main network at the main site and changed the 3 Remote site ASAs to point to the new DNS server in the DHCPD options, none of them could ping any local host names to the DNS server at the main site they were now pointing too, but external host names { URL} all translated and pinged fine.
From a laptop on one of the remote sites, we could ping the new AD/DNS server(192.168.0.3) and the old AD/DNS server(192.168.0.2) and everything else at the main site, and telnet to port 53 showed successful across the Easy VPN from the Remote site to the new server at the main site. When wire shark was added to the new DNS server at the main site, the DNS request and replies for {URL}, for example, came and worked fine, but any requests for local resources never made it to the server from the remote sites.
A reboot of one of the Remote Site ASA's corrected the issue. Then I rebooted the other two remote site ASAs, and now DNS was working fine for everybody. I had also tried clearing the ARP cache on the ASAs before resorting to rebooting them. I also tried rebooting the laptop thinking the local DNS cache needed cleared before resorting to rebooting the ASAs. I'm struggling to understand why external, public host names made it through and resolved from the remote sites to the new server at the main site, but anything local failed before even reaching the new server(The new DNS server could resolve requests made by computers at the main site, but the remote sites that traverse the Easy VPN from the ASAs failed). The new AD/DNS server is the only server configured for DNS for all remote site computers.
Is any of this making sense? I'm wondering if clearing the x late or local host tables would have corrected it without having to reboot. I'm just trying to grasp the understanding here and figure out what happened.

View 4 Replies View RelatedWe have a BT Infinity broadband circuit which terminates at a vdsl modem, I've plugged an ASA 5505 into the back of this modem and gone through the ADSM quick setup wizard (yes I'm that much of a beginner!) The config that's been generated is pasted below, the symptomns I'm seeing are;
The ASA is setup with PPPOE on the internet connection, I assume this is correct as if I do a show IP on the ASA I'm getting an IP address that has been assigned, if I change the password to the wrong one then I get no IP (as expected).
If I ping from the ASA to an internet connection I'm getting "no route" error messages, if I try a "ping outside x.x.x.x" then I get no repsonses.
The ASA can ping it's external IP, the client machines can ping it's internal, however nothing appears to be able to get out.

Why when I try to reset Cisco ASA 5505 by pressing the button behind the hardware nothing happen? Just via software I can reset it?
I bought the hardware an year ago and I've never used, the problem that I don't have the blue cable and via software connecting to PC doesn't work.
I just got a Cisco asa 5505 with the next OS and ASDM info ASA 5505 OS 8.4(3) ASDM 6.47 I configured and enter all rules to allow incoming traffic to LAN but it's not working also, I have one host inside that is configured in a second IP and create the rule to allow traffic to it but it doesn't work too.
Problem 1 I have VNC running in port 5900 tcp and I want to connect from Internet using port 6001 and this has to forware the connection to the real VNC port. In the configuration I have a few host with the same configuration but I use different outside port to get it.
Problem 2. I have a second IP with services: SMTP, HTTP, HTTPS and port 444 all TCP forwarding to a server in the LAN.
Facts: SMTP. Every time that I do telnet to the second IP looking for the SMTP port, the firewall doesn't let the incoming connection goes through and the LOGGING screen doesn't how that connection.PORT 6001 (outside)this port is configured to work with the IP in the outside internface and it was to send the incoming connection to a host inside to the real port 5900.Can any one check my configuration if I'm missing anything? for sure I'm but I didn't find it. Bellow is the configuration, I masked the Public IPs just left the last number in the IP, also I left the LAN network to see better the configuration.

We have 110mbps internet service. When we have the 5505 behind the cable modem, our speed drops to 55mbps or so. If we remove the 5505, we see the full 100mbps. I assume the 5505 can handle the speed; if so, what other things should I be looking at?As an aside, we used to have 50mbps wich worked fine, then the ISP upgraded to 60mbps and the through put dropped to 30mbps (It always seems to be half)
