I have a network with multiple voip gateways run by an Asterisk server. Among others, I'm using a Cisco 1760 with a VIC-BRI as ISDN gateway.To standardize the dial patterns between these different systems, I have decided to systematically translate them to e.164 before sending them from one system to the other.

View 1 Replies View RelatedAny OID to determine the number of registered AP's on a WLC (specifically the AIR-CT2504).
I've got both of the Airespace MIBs and have browsed through them but I can't seem to find the correct location. I can find a list of all of the AP's registered but our monitoring software doesn't have the ability to 'count' that index. As such, I'm looking for a count/summation of the total number of registered AP's via SNMP.
There is nice c2900PortNumberOfLearnedAddresses table in C2900-MIB, but it's outdated and not supported by modern switches.Is there similar table for modern switches? Most interested in Catalyst 2960 and 3750.
View 2 Replies View RelatedI'm developing a project where I use the SNMP protocol to discover the network. By discovering the network I mean go through all the routers and switches and retrieve the IP routing table from routers and the forwarding table from switches. With the routers I have no problem. For the switches I need to know for each port the MAC addresses and the Vlans. Basically it's use SNMP to find a port number from a MAC address. To do that i followed this tutorial: [URL]
The problem is that I'm using a Cisco 3725 Router with IOS 12.4 (21) and a NM-16ESW module to work as a Switch and when I use the OID .1.3.6.1.2.1.17 corresponding to the BRIDGE-MIB as it follows:
snmpwalk -v2c -c myrouter 10.1.1.5 .1.3.6.1.2.1.17
it returns:
SNMPv2-SMI::mib-2.17.1.1.0 = Hex-STRING: 00 00 00 00 00 00
SNMPv2-SMI::mib-2.17.1.2.0 = INTEGER: 0
SNMPv2-SMI::mib-2.17.1.3.0 = INTEGER: 4
From this I guess there's no information on the router about Vlans or anything. Other thing is that when I use community string indexing it returns a timeout. My theory is that this version doesn't support indexing but I don't know.
how can I get the Port Number from a MAC address from this "switch" (it's a router working as a switch) using SNMP?
I have some tunnels which terminate to my home router. I'm allowing the other ends of the tunnels to use my voice setup. I need to prepend *67 to all called numbers which don't originate from my house. I don't want people calling my home number based on the caller-id number they see when someone across one of the tunnels calls.
So if 5008 calls 212-333-4444 I want it sent to my provider as *672123334444. If 5001 calls a number, I don't want it touched. Can I do this? I can use IOS or CUCM here.
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. According to this [URL] and some others I seen DNS payload can also be translated in NAT configuration.How can I doing it with the VPN3000 box ? On my configuration DNS payload aren't translated, but it is maybe an option I need to set or unset !
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)
I am trying to change a static nat entry from this:

no ip nat inside source static tcp 192.168.0.246 443 interface dialer0 443 But I am getting cisco2800(config)#%Static entry in use, cannot remove.
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'm seeing plenty of these errors on my ASA5510. The ip's in question are IP's that my ASA is assigning VPN connection from my General IP pool.
Here are some examples:
<179>%ASA-3-305005: No translation group found for udp src External:172.16.50.112/29239 dst External:172.16.50.140/10009

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?

I dont want to change the original setup .I am trying to implement NAT on the local router such that
- any traffic from SUB-TEST that enters the inside interface and is going to Server1 then change the destination and NAT it to TESTServer 2
- all other LAN traffic is allowed to go to server 1.
i am using a 1941 router for this
i am trying to find out if it is possible to have a translation rule fail over to a second server if the primary is down on my cisco pix515e.so for instance having an external ip address of 82.x.x.x mapped to an internal ip of 10.x.x.1
If 10.x.x.1 is down then 82.x.x.x should be mapped to 10.x.x.2.The reason i am asking this is i also have 2 css11501 load balancers and would like to have our staging servers primarily sat on one with secondary connectioin to second, production on the other failing over to each other if one is down. The load balancers will be connected to different ports on the same firewall.
Recently upgraded to an Asa 5512x from a pix 515e. I have an Ipswitch secure MoveIT server on the dmz1 interface that needs to be accessed from both the inside and outside interfaces. I have setup a static nat from the outside to the dmz1 and it works, I can also connect from the inside interface. Now I need the MoveIT server to access the DNS server and email server on the inside interface so it can send notifications. On the pix I just created a static from the inside to the dmz1 using its own IP address - static (inside,dmz1) 192.168.1.7 192.168.1.7 net mask 255.255.255.255. I would then add the access-list to allow. How would I set this up with the Asa 8.6 commands?
