Some network pros have setup our Cisco 3620 many years back during implementation.
I've just added a new server, with new ip, wanted to change the ip of ip nat translation in this router.
I did a show run, the config is this;
interface FastEthernet0/0
ip address 57.31.132.116 255.255.255.240
no ip redirects

I have a server in a DMZ of my 8.4 ASA with nat:
object network FTP-SERVER
host 192.168.1.102
nat (dmz,outside) static interface tcp ftp ftp
And that's working well. However, I now need to translate the source address of connections from the outside to the FTP server as well. The aim is that the source address of packets when they reach the FTP server is an address on the DMZ subnet (as the default route for the FTP server now needs to be something else, not the ASA) as well as this outside-dmz NAT. I thought overloading the DMZ interface of the ASA? Or another IP in that range?
I need to change the source IP of a packet for one of my NAT's.I currently have an Cisco 1812.I have an PPPoE connection as Dialer 0.I have another VLAN that is connected to an Netscreen SSG5 VPN gateway via another Cisco switch.I have a vlan trunk between the switch and the 1812. What I would like to achive is the following :-For any traffic going to the following three ranges make it apear as if it was coming from the VLAN50 address [code]I can ping my netscreen on 10.27.30.255 fine from the Cisco 1812. But any other PC fails, as for some reasion the traffic has a source of my Dialer 0 interface.How can I write a nat to change the source just for the tree destitnations ?

host 1 <-> R1 <-> R2 <-> FW<-> host2
host 1 is configured to send syslog to host2, however due to firewall ACL is not configured, this has caused a spike to 99% in R1 which already has 70% - 80% cpu.
My questions are :
1) Even if the firewall is sending RST back to host 1, it should not caused an 20% cpu increase in R1 cpu. Why this is so? Router model is 3620.
2) How do i prevent this from happening in future? This could potentially allow someone to send random traffic to hosts and cause network performance issue. Is there a way to turn off the RST response from the Firewall? This is an Cisco ASA.
I have a Cisco 3620 router and I am trying to get internet access. My isp is comcast. All modem lights seem to be operational. But I do not have internet access. I can ping anything other then the router and I am on a home network.

I config my E0/0 Interface with "ip ospf network non-broadcast" command, I want this interface to use uni cast to hello neighbor.
As I issue "neighbor x.x.x.x" under ospf process, it told me that: OSPF: Neighbor command is allowed only on NBMA and point-to-multipoint networks. I am sure that there are no any typo, and show ip ospf interface e0/0 says it's been an NBMA interface, so what's wrong with this router?

I just finished setting up a bundle of (2) T1's in a multilink bundle and I'm having issues with one of the T1's not wanting to join the bundle.
The router I'm using on the remote office location is a 3620 router running code c3620-i-mz.121-1c.bin
The campus router which is a 7206 is setup the same exact way with multilink 240 and like I've said, serial 0/0 is joined to the bundle just fine, so we are running off one T1 connection.
The serial interface that is not working is: serial 0/1
Here is a show-run:

currently I face problem with outside nat translation and Im not sure how to solve it. I gotta 881 router
int vlan1
ip address 10.10.10.1 255.255.255.0
ip nat inside
[code]...
and remote server 100.100.100.25 routed to interface fa0/0. So the problem is that hosts from V lan 1 and V lan 2 want to communicate to this server, but they cannot route, which means, that I have to "give" them some IP from their range as fake address of this server and translate it. So I did
ip nat outside source static 100.100.100.25 10.10.10.7 (for Vlan 1)
ip nat outside source static 100.100.100.25 20.20.20.7 (for Vlan 2)
but I get
% 100.100.100.25 already mapped (10.10.10.7 -> 100.100.100.25)
As far as I understand router doesn't allow this translation, because if the communication would be started from outside (initial packet would come from server side), router wouldn't know how to translate its source address.
I am going with ASA 5520, know how many NAT translation is possible.

We have a VPN configuration currently using a VPN3000 device.

View 1 Replies View RelatedI have 5 static public IP addresses assigned by my ISP. I like to use one of these static public IP addresses to access one of my PCs in my office from the outside. So I like to configure something like:65.11.22.44 <-> 192.168.1.100.This translation is good for all protocols and all ports. Where I can configure this on the DIR655?
View 2 Replies View RelatedWe've got an application that is running on our LAN that is using IP addressing to connect to the server (they refused to use DNS).The server is now being moved to a VM which will be on a different subnet. 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? I want to have the devices pointing at their hardcoded IP address off 1.1.1.10 and NAT the destination to the VMware servers IP 2.2.2.10? Is this possible using cisco NAT?
View 13 Replies View RelatedI have a nat and vpn setup on my Cisco 2801 router.Everything is working as expected except the NAT. I have a single static nat translation but it only works for inbound and not outbound. Going outbound, it uses the default overload nat address of the outside interface. [code] I want to add another mailserver. But I fear if one mailserver were to get black-listed, they would both be reporting there ip address as the same address (the one on the ethernet interface) which would blacklist both mail servers.Again, inbound nat works ok, but outbound is just using the IP of the ethernet0/0 address.

I'm trying to migrate from olda PIX to newest ASA 8.4.1. Everything seems to be good except the static NAT. [code]
The inside interface uses implicit rule. ( permit any less secure network )
Although te above config the ASA logs the following.
TCP access denied by ACL from 94.94.94.94/2003 to outside:86.101.228.221/80
The 86.101.228.221 our public Internet IP whic are used as outside IP also.
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 network NATED-11
host 20.20.20.11
object network REAL-2
host 10.200.200.2
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
nat: untranslation - outside:20.20.20.11/21 to inside:10.200.200.2/21
nat: untranslation - outside:20.20.20.11/21 to inside:10.200.200.2/21
nat: translation - outside:20.20.20.252/37924 failed - port is not found in xlate(0-0)
[code]....
To make it work I need to modify the nat rule to sth like this (translate source of client to inside inteface of ASA) nat (outside,inside) 1 source static any interface destination static NATED-11 REAL-2 service SRV-FTP SRV-FTP / why its not working in the first place? aaa I forgot to mention that both modes of FTP were tested (passive and active)

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?
