Cisco Firewall :: ASA 5510 - How PAT With One Public IP To Two Internal Servers
Sep 18, 2012I've tried a bunch things but it didn't work, I'm about to gave up! :-/
I have the following scenario:
ASA5510 - v8.3(2)
Interfaces
ETH0/0 = outside = 189.xxx.xxx.129
ETH0/1 = inside = 10.xx.1.15
[Code]....
What should I do to get the SIP and 8080 port working on my Public IP, likewise just as access from my browse the http://189.xxx.xxx.129:8080 and get through directly to my internal server 10.xx.xx.61 ?
Cisco Firewall :: ASA Version 8.3(2) - Internal Traffic Not Allowed
Jul 29, 2011i have reviewed this configuration a couple of times and I am not seeing my error. I have two internal subnets, in different VLANs with the ASA being the default router. The internal zone works fine, but the zone called wireless on VLAN 13 doesn't. The firewall blocks all communications and the rules look correct to me. I want all traffic on this wireless subnet to be allowed to cross over the firewall and NAT to the outside interface, just as the inside zone does.

Apr 2, 2013One of our vendors requires using a public ip address to setup a site-to-site IPSEC vpn. We only have one public ip address and that will be used for the vpn endpoint and for internet access for the local network. I've setup policy NAT from our local network to the outside interface. I'm also using the outside ip address for the crypto map. The tunnel setups successfully and the Tx count increases anytime I try to ping the remote network, but the ping fails and the Rx count does not increase. According to our vendor, we should be able to ping the remote network and connect using port 443. When trying to connect using port 443, I see a SYN timeout in the logs. I'm not sure if the problem is on their end and they're rejecting our traffic, or if something is misconfigured on our end. I'd like to make sure that I have everything configured correctly before I go and point fingers at them.
Local Network - 10.10.9.0/24
Remote Network - 20.20.41.0/24

Apr 27, 2013I have a doubt on how do nat 2 internal ip addresses to 1 public ip for FTP uses.
As I know Cisco ASA cannot use to nat 2 internal ips to 1 public ip as the ASA cannot read the host header. It there anyway to control it by using acl or network object group?
My current configuration for nat 1 internal ip to 1 public ip:

Dec 19, 2011I have an ASA 5505 configured with internal network, a DMZ, and a VPN on seperate subnets. The implicit rules allow my internal client computers to connect to the web servers on the DMZ IP, but I can not connect to the public NAT address from the internal network. I have a DNS server on my internal network and it does resolve to the public IP correctly. NAT seems to be working correctly because if I go outside the network and connect to the public IP or qualified name then I can get to everything correctly. I do not see any messages in the Cisco logs and the packet trace tool shows the route of http from an internal IP adddress to the external (NATed) address is allowed.
Specifically, I can go to http://192.168.1.121 from the internal (192.168.0/24) network, but I can not go to http://72.22.214.121 (the NAT address) from the internal network. If I am outside my cisco then I can go to http://72.22.214.121 easily. [code]

Nov 21, 2012New to the ASA 5505 8.4 software version, but here is what I'm trying to do:
-Single static public IP: 16.2.3.4
-Need to PAT several ports to three separate servers behind firewall
-One server houses email, pptp server, ftp server and web services: 10.1.20.91
-One server houses drac management (port 445): 10.1.20.92
-One server is the IP phone server using a range of ports: 10.1.20.156
Basically, need to PAT the ports associated with each server to the respective servers behind the ASA 5505. Is anything missing from this config? Do I need to include a global policy for PPTP and SMTP? [code]
Cisco Firewall :: Migrating Netscreen Firewall To ASA 5515 Version 8.6?
Mar 5, 2013I am currently migrating a netscreen firewall to a asa 5515 version 8.6 The issue is setting up the management connectivity.
basically the management IP of the cisco asa is not advertised. But, we want to route a management IP through the management interface to interface Gi0/2.
so IP of management interface is say - 216.10.100.10. and the IP of the inside interface is say - 198.1.1.10/24 on our router we have a static route sending 198.1.1.0/24 to next hop of 216.10.100.10 (management interface of cisco asa).
On the Cisco ASA can I send the traffic to the inside interface and manage the firewall via ssh that way?
Cisco Firewall :: 5510 - Transparent Firewall Installation Using ASA Version 8.4(3)9
May 14, 2012 I'm trying to install an ASA 5510 transparent firewall using ASA version 8.4(3)9 but I don't understand how traffic will ever pass through my firewall if both interfaces are on the same sub net(V lan) as the host and it's default gateway? The reason I'm doing this is were installing UAG (or Direct Access) and the UAG appliance need to have public IP's but still be behind a firewall (see attached diagram).
Looking at the documentation (which all seems to be for 5505's running 8.2) it almost seems like i need to have the transparent firewall 'in-line' to the ISP router?, but this router services another IP address range on another v lan for other (routed) firewalls (not shown on diagram) so putting it 'in-line' is not possible. Surely this can't be the case can it? If not how is it supposed to be cabled up and configured so packets go through the firewall?

The new block is a /29 range and I would need to use just two of those IP addresses. Here is the situation I am facing.A company we partnered with wants to set up a VPN, they will send us 2 Cisco 861s to put behind our ASA. Is it possible to assign these 861's with public IPs from the block that we are not currently using? (the /29 range)? I know that it might require an upgrade to the Security Plus.

May 2, 2013The client I am doing work for as ASA 5505 at a remote location that is using Cox Communications for the ISP. The ISP assigned 5 static IP addresses, but we only need 1 for this location. However, that is the minimum you get no matter what. The issue is that the subnet mask is a /25 and what they are telling me is that the ASA is grabbing all the IP addresses in that range. They asked if there is anyway to keep the ASA from grabbing those IP addresses. Now, I have never run into this issue before with a provider. The gateway is in the /25 subnet, so going to a /30 isn't an option.
