We have a router that was installed a few months ago which has the following version: 15.1(3)T
I am unable to reverse telnet to a new ASA firewall, however when I move the console to a second older router with an older version of code I am able to reverse telnet
Are there any known bugs, issues with version 15.1. I use the following command as normal: telnet x.x.x.x 2001
I have a new 877 that I am using for internet traffic for 3-4 internet only devices.I also have a clean network that i want to insure no cross contamination. However I plan on rolling this out to many sites, but for management I was hoping to set up a reverse telnet to the console port from our one of my clean switches. which should allow me to keep the units seperated and allow me to manage changes etc remotely. Unfortunatly there is no Aux port on the clean switch (3560). Is there still a way to acheive this? can i configure one of the ethernet ports to connect to the console of the 877?

View 2 Replies View RelatedThe network is set up like this.
Host -----> 3750 (classic) running IPSERVICES stack ----> 3550 router -----> VPN 3005 Concentrator.
IP routing is disabled on the 3750 (it's acting solely as a switch) IP routing is enabled with an EIGRP process running on the 3550 router that has the network for the 3005 broadcasting.
I can ping the vpn 3005 concentrator from a telnet session in the 3550 but not from the 3750.I can ping between the 3750 and the 3550 vlan management interfaces. Visually speaking it's like this
3750 ------> 3550 [Success!!!!]
3550 ------> VPN 3005 Concentrator [Success!!!!]
3750 ------> 3550 --xxxx--> VPN 3005 Concentrator [Timeout....]
I know this because I tracerout to the 3005 from the 3750 and it resolved the default gateway configured for the 3550 properly but then started timing out.
The 3750 is trunked to the 3550.
3750 is vtp client mode
3550 is vtp server mode
I'm wondering if there's a layer 2 issue involved here as it is a VTP domain and maybe it's not returning properly.

Router 1 : Cisco 871 w
Router 2 : Sagem – F@st 3304 v2
I have 2 data centers conencted via WAN and each has their own Internet conenction. One of the site's Internet is close to maximum bandwidth and we want to use the second site's Internet for future connections. The problem is the core switches in each site has a default rout to their local firewalls, so even if I can NAT on the firewall, the return traffic goes out whichever firewall is local and will fail.
So, my plan is to change the source IP address of the packets to be an address on the inside interface's LAN subnet. That way it is routed back to the proper firewall. I am able to do this with the following code, but this code only works with a static one to one NAT. I am limited in public IP addresses, so I want to NAT on a per port basis. Each time I try to change the any any to a specific port, it fails.

I am currently trying to apply a reverse NAT on asa 8.2 and not sure how to do this. I have done this on asdm 6.2 for asa 8.3 but the options are not simiar on 8.2. Is there a CLI equivelant?
I am trying to Achieve the object below for any traffic coming from outside interface to the inside interface with any source address to destination 10.X.X.58 then translate it so that it become 192.X.X.X to address 192.X.X.58. This is so that communications can traverse internal network as the server is not ona DMZ.
I have done this on 8.3 (shown below) but do not know if it is possible for 8.2, I have tried replicating the same command on 8.2 but commands are not recognised.
nat (outside,any) source static any 192.X.X.X destination static 10.X.X.X 192.X.X.58
Should I just upgrade to 8.3? never done it before so not sure of the consequences.
After upgrade to 9.0.1 from 8.4 I have problems with reverse dns resolving, like this:
named[2679]: DNS format error from 193.0.9.1#53 resolving 82.64/27.195.26.72.in-addr.arpa/PTR for client 127.0.0.1#37124: question section mismatch: got 90.64.195.26.in-addr.arpa/IN/PTR
Only solution I found is to disable inspect dns, which is not very good.

Can any tell me how to do this or at least point me in the right direction to obtain the user manual for basic instructions?

i have 68 sites with Routers. On each site I have one equipment DIRECTLY connected to the Router that needs to be accessed by telnet port 23.
I have 15 off this sites that the access via telnet to the equipment’s connected after the routers are not working. These sites are using Router Cisco 3925. The other sites that are working are using Routers Cisco MWR 2921.
Both router models are running the same configuration with no filter on it.
The equipment’s after the routers are all accessed directly via telnet without the router. If the router is directly plugged to the equipment the 15 sites with Router Cisco 3925 are not accessed via telnet.
There is any bug related with the IOS version that Router Cisco 3925 is using?:

I'm new to working with the ASA 5505 ,VPN and reverse NAT.
The basic setup is as follows. I'm trying to setup a IPsec site to site tunnel with reverse nat on the remote side.
I have as the tunnel up and it passes traffic. I have setup reverse NAT for 172.x.x.1 to translated IP 216.x.2.101 my ASA also has an IP address of 216.x.2.102.
Any connection from 172.x.x.1 to 216.x.2.1 should appear to be comming from 216.x.2.101
When I ping or telnet from 216.116.86.1 to an open port on 216.x.2.101 I get the banner from 172.x.x.1, seems like it is working.
However in my setup I'm only given a singel IP that of the NAT address 216.x.2.101, so when I remove the IP address assigned to the inside interface 216.x.2.102. all conductivity is lost.
When I set the inside interface to 216.x.2.101 and I setup a static NAT rule for 172.x.x.1 to 216.x.2.101, I get a message that says all traffic will be redirected and I will be unable to connect to the ASA.
Once thats in place, and I make any connection from 216.x.2.1 to 216.x.2.101on any port I get a connection but then it's reset, I no longer get the telent banner I was expecting.
My running config is,
ASA Version 8.2(1)

hostname ciscoasa
[Code].....
My network consists of a router and a ASA5505. The router has a serial connection back ot HQ. The ASA has a VPN connection back to HQ. I want the network traffic destined for HQ to travel over the VPN connection until that connection is no longer valid (down). I've been told that RRI is the way to go but cannot get it to work. I get one of my routes to show up in the router but that's it (and not as a static route). Also I don't want the routes to be injected if the VPN connection is down. But I do want the VPN connection to be the preferred connection.

Deny UDP reverse path check from 10.100.100.102 to 10.100.100.255 on interface SPECTRA-LAN
This is because interface SPECTRA-LAN (VLAN50) is the interface connected to the network with ip 10.100.100.0/24 but the interface do not have a ip address so it does not exist in the routing table I believe?However interface INTERN do also belong to network 10.100.100.0/24 which also is the management interface and the default route for hosts in network 10.100.100.0/24, but has no vlan.
1. move the management0/0 to SPECTRA-LAN and give SPECTRA-LAN ip 10.100.100.1?
2. give SPECTRA-LAN a ip address in the 10.100.100.0 range?

View 3 Replies View RelatedMy Setup / I've been lurking on here a while, working hard to understand the basic networking concepts and eventually pursue the CISCO certs. I bought a lab and have since managed to setup a four router config (2610XM-DTE, 2621-DTE, 2501-DCE, and a linksys E1000 with routing, DHCP, and NAT turned off to make it a wirelss access point) with three switches (2@2950 and a 2924XL).
So far, I have managed to bring in my public IP using DHCP, and setup PAT. The network is fully functional, I can ping every interface, and reach the web on host PCs from any switchport. I am also able to telnet into the FastEthernet interface IPd with my public address.
My Issue : My concern right now is in feature support. I recently read on here that CISCO does not support UPnP, and due to my limited resources, I am using the only public IP I have to allow remote testing/learning on my lab. The issue is that I also have a PS3 and XBox 360 on this network that is requiring UPnP for certain online games and features.
The only solution I can see to this problem is to return my public IP back to the E1000 router, which is running RIP Version 2 (white papers said version 1, but a debup ip rip showed that updates were being ignored due to illegal version), and then poing my other three routers to it for outside access.
The questions I have in this scenario:
1. Will NAT still function if I use the E1000 and set the interfaces connecting to it as ip nat inside? I'm assuming that PAT is already hardcoded onto the router to allow for multiple connections to public IP space.
2. If my IP is 68.X.X.X, I set the E1000 to an IP of 192.168.1.1 and the FastEthernet it connects to is on my 2621 with an IP of 192.168.1.2, would it be possible to telnet into 192.168.1.2? If I were to forward port 23 out of the E1000 to the 192.168.1.2 address. Will my login and password for line vty 0 4 understand the request if the original telnet was to my public IP?
3. If all of that is just non-sense, is there another work-around that allows me to acheive UPnP through my E1000, while retaining telnet ability to my lab so I can try things in different scenarios or while I'm away from home?
We have a singe IP Address in the Internet and want to forward SMTP traffic that hits our ASA Outside Interace to the internal Mailserver.And we like to forward Http Traffic to our Webserver.
Example.
212.23.23.23 Port 25 -> 192.168.1.100 Port 25
212.23.23.23 Port 80 -> 192 168.1.200 Port 80
How do i acomplish that. Which NAT rules do in need?
I have the need to do an outbound NAT redirection. So what I mean is this. I have a custom program that uses SSH to port 22 from a server inside the ASA firewall. This goes out to a server on the Internet over port 22. The ISP of the SSH server told me that they changed their SSH port from 22 to 2102. So instead of changing the custom code on the developed application on the server... I thought it would be easier to do a OUTBOUND NAT redirection for the ASA to see port 22 from the server and redirect it OUTBOUND to port 2102.
so for example:
The server is at 192.168.0.2 and it uses a program to initiate SSH traffic to 205.246.1.1. The server sends to port 22 but I need it automatically changed on the firewall to port 2201 at 205.246.1.1.
It is a Cisco ASA 5510. The server at 192.168.0.2 does have a fixed IP address on the outside with INBOUND NAT for things like port 25 (mail) traffic etc. Lets pretend that was at 64.18.23.60.
I have some legacy (read: old) audio equipment that used leased lines to run, no way to convert them to IP internally. They have x.21 and v.35 interfaces on them.
Is there a way i could use something like an old 2600 series router and run it in reverse, like just using them as a media converter to shove the v.35 over into IP land?
I'm not interested in buying newest latest greatest (these audio codecs are upwards of $5k a pop to replace, x2 for a complete link), i'm just curious if i can turn a WIC-1T into the interface for these boxes and do a direct route to another 2600 on the other end with the same configuration.
This would essentially turn the WIC portion into the local side and the ethernet into the WAN side.
