View 2 RepliesIn my router I can set rule that all traffic incoming to router's extAddr:8888, is forwarded to my intAddr:8888. But I also need reverse rule that packets originating from intAddr:8888 are translated to extAddr:8888. Can I do that? What technique can I search on google to find more information, because it is not port forwarding. I would calll it reverse port forwarding or static port address translation, but I do not find anything useful in internet searching these keywords.

In the documentation for the Mitel border gateway it wants me to set up 2 external IP's on my ASA one to allow 443 traffice into the MBG, and another for 443 traffic that needs to be forwarded to port 4443 for the MGB in the DMZ. My problem is I don't know how to do this. the MBG only has one IP, and I need to have 2 different URL's mapped to two different external IP's both externally using port 443, and one of them forwarding to 4443 on the DMZ interface.

How Stuff Works "How Network Address Translation Works"."This is where NAT (RFC 1631) comes to the rescue. Network Address Translation allows a single device, such as a router, to act as an agent between the Internet (or "public network") and a local (or "private") network. This means that only a single, unique IP address is required to represent an entire group of computers." so let's say 6-7 pc's can have access to the internet using the same IP. doesn't this causes any problems? what if one of those pc's was used fore doing something illegal? how can they spot it later on? or what if 2 or more pc's access (from that subnetwork) access the same website with the same IP?

The supplier is now concerned that there will be a big down time due to him having to reconfigure each device (about 100) with the new server IP. If the server was external I know I'd be able to do NAT on the FW to make this work but can it be done internally on my 6500s?

View 13 Replies View RelatedIs it possible to perform static Nat's through an internal network?I have a ASA 5510 with a public outside interface (let’s call it 68.68.68.1), and I have an inside private IP address (192.168.1.2/24). The inside IP address leads to a 4900m with that interface being configured with a 192.168.1.1 (no switching). On the 4900 M I have several VLANs one of them is an internal DMZ of sorts. (192.168.2.0/24). Within this DMZ network are several Web servers which need to be associated a public IP address (68.68.68.x).
Every time I configure a static Nat to associating a public IP address with an internal IP address within the DMZ, packet Tracer on the ASA informs me that the packet gets dropped at the static Nat and I cannot figure out why this is so.Safe it to say my question still stands is it possible to Nat (68.68.68.222 to and 92.168.2.60) given the configuration above, and how would I go about configuring in such the manner above so that I acn apply static nat through the 192.168.1.0 network to reach the 192.168.2.0 network.

I have some issues with Twin PAT on ASA (8.4.2), there is sth I dont udnerstand FTP server is on the inside and client is in outside.
I did sth like this

object service SRV-FTP
service tcp destination eq ftp
nat (outside,inside) source static any any destination static NATED-11 REAL-2 service SRV-FTP SRV-FTP so teoretically there should be a problem in NAT cause there is a second channel for data etc. BUT according to docs "For applications that require application inspection for secondary channels (for example, FTP and VoIP),the ASA automatically translates the secondary ports."
The problem is that it doesn't work at all and got the syslogs
Debug on ASA shows
ASA5510(config)# nat: untranslation - outside:20.20.20.11/21 to inside:10.200.200.2/21

However, either way I have the same problem. A client can successfully connect and access servers but just once. When the client disconnects and tries to connect again there is no access to the servers even though the VPN tunnel appears to be up. I've tried multiple versions of the Cisco vpn client SW and all behave the same: 1st connection can access servers, subsequent connections can't. I've also tried a second (different) client after the original connection and still no luck. If I reload the router the client can get the vpn connection and access the servers but if the client disconnects from the vpn and tries again there is no access to the servers.
I've also tried it with and without NAT but it doesn't seem to make any difference.
The config generated using CCP is as follows:
version 15.0

View 1 Replies View RelatedWe already have IPSEC VPN connectivity established between sites but would like to introduce some resilience/redundancy at a remote site.
Site A has an ASA with one internet circuit.
Site B has a Cisco 2911 with one internet circuit and we have established site-to-site IPSEC VPN connectivity between the 2911 and the ASA.
Prior to getting the new internet circuit, Site B had a Cisco 877 with an ADSL line which are still available but aren’t currently in use.
The internet circuit at Site B has dropped a few times recently so we would like to make use of the ADSL circuit (and potentially the 877 router too) as a backup.
We thought about running HSRP between the 877 and 2911 routers at Site B and, in the event of a failure of the router or internet circuit, traffic would failover to the 877 and ADSL.
However, how would Site A detect the failure? Can we simply rely on Dead Peer Detection and list the public IP address of the internet circuit at Site B first with the public IP address used on the ADSL line second in the list on the ASA? What would happen in a failover scenario and, just as important, when service was restored – I’m not sure DPD would handle that aspect correctly?
I’ve read briefly elsewhere that GRE might be best to use in this scenario – but I can’t use GRE on the ASA. I have an L3 switch behind the ASA which I may be able to make use of? But I don’t want to disrupt the existing IPSEC VPN connectivity already established between the ASA and the 2911. Can I keep IPSEC between the ASA and 2911 but then run GRE between the L3 switch and the 2911? If so, how would this best be achieved? And how could I also introduce the 877 and ADSL line into things to achieve the neccessary redundancy?
I am having cisco 2911-sec-k9 router.
And I got 2 internet connections from isp one is static ip leased line and the other one i dsl dynamic ip one.

My dsl line in 100 mps and my leased line 2mb dedicated.
I configured the router as with some example config i got on internet my internet is fine but load balancing not happening and i configured the REMOTE ACCESS VPN . I am able to connect the remote access vpn but no communication through remote access . i cannot reach any device through remote access.
Note: if load balancing is not possible how i can configure for internet traffic use dsl line and for remote access vpn and live exchange port forwarding through leased line.

I am attempting to get a solid setup for a remote office we have going up and I am running into little issues that I cant seem to get around.
Basically, we have a remote office that will have dual ISPs, one hard wired circuit from a local carrier and the other will be a Verizon 4G router that plugs in via Ethernet and hands out DHCP to my Cisco router.The Cisco router is a 2911 with IP SLA configured. I have it setup to ping my DC out one interface and if that fails, it removes the default route and injects a new default route from the other ISP,
The problem I am having is with the VPN. I figured using EZVPN would be the only solution because the Verizon 4G only supports DHCP so I have to be able to connect from a dynamic remote host. The other caveat is that failover needs to be seamless as we have no person onsite that can troubleshoot. Its fine if it takes a few minutes, but the VPN just needs to come back up on its own without any intervention.
I attempted to setup two different EZVPN crypto maps on the router but realized you can only have one inside cryptomap per interface, which would cause a problem with the internal network. I thought I could just create subinterfaces off the router to have two inside interfaces to work with but that wouldnt have supported because they would now be on different subnets.
I decided that adding an ASA5505 behind the router may be the simplest solution. Use the router only for the purpose of handling routing between the two ISPs and performing NAT out the interfaces. Then use the ASA to do EZVPN from. This works well but there are some issues I am trying to work through.
First, when the ISP fails over to the backup, the NAT translations have to timeout before things start working again. For a constant ping, this is fine, I have the timers set down to 15 seconds for NAT timeouts and after 15 seconds the ping picks right back up again. However, this breaks the EZVPN. The ASA keeps trying to bring up the ISAKMP nearly every second, which keeps resetting the countdown on the NAT timeout for the remote EZVPN server. Because of this, the VPN will never come up until I manually clear the NAT translations on the router. So my first question is this; is there a way to adjust the timer that the VPN uses to try to bring the tunnel up? I tried the crypto isakmp keepalive command but that didnt work, it looks like it doesnt work with EZVPN.
The second issue is really with the IP SLA and is only an issue because of the first issue I mentioned. When the router first comes up after a reboot, both the primary and secondary interfaces come up. However, since the primary default route is only injected into the routing table once IP SLA is up and can reach its destination, the secondary route gets injected initially and the VPN comes up over the secondary ISP. In a few seconds, the primary default route is injected, changes the path and because of the NAT translation, breaks the tunnel and never comes up again because of the first issue with the VPN tunnel renewing the NAT translation continuously.
I could easily go out and purchase a $100 Linksys router that will do the failover and clear its NATs and everything, but I need better reliability out of the hardware than that. There has got to be a way to do this on a Cisco device since consumer level equipment can.
I have a 2911 router where I was configuring the device to allow remote desktops connections. Everything is working properly, but for some reason my ACL has disappeared.
