Here are two traceroutes both to 82.195.128.132. One results in the name ns1.hosting 365.ie and the other in the name mail.hosting365.ie. Why the difference? [code]
View 2 RepliesTo show up the ASA as a hop in a traceroute, one can use the 'set connection decrement-ttl' feature in a policy map.During my tests I recognized, that this behaviour only affects IPv4 traffic.
An IPv6 traceroute still does not show the ASA as a hop.How can I configure the ASA to show up as a hop in an IPv6 traceroute?The ASA is a 5520 with v8.4(1) installed.
where the host names do not properly resolve with the right ip address.Example, I ping a host name, it gives me an IP, but when I VNC into the workstation, it is a totally different host.
I can find ip address of any website from domains by using simple command [URL] in command prompt.I wonder how I can find the domain names from ip addresses.For e.g. I would like to know the domain names of ip - 207.232.22.200
View 7 Replies View RelatedI have an issue with LMS 4.1 where the DCR names of several devices repeatedly revert to the IP address. I am trying to stage some devices for deployment. The initial 5 devices were staged and are now off-line. A subsequent set of 6 devices is on-line and accessible from LMS4.1. The device names on the off-line devices are stable. The device names of the on-line devices revert back to an IP address every day. From device management, I go in and change the display name and the host name from the IP address to an alphabetic host name. When I go back and look at it the next day, it has reverted to the IP address.

View 2 Replies View RelatedWe all know that MS traceroute and *nix traceroute work a bit differently. *nix works by sending UDP packets with low ttls to random high UDP ports.

View 1 Replies View RelatedI'm working as a network engineer for a service provider, and we had just gone through a pretty large scale upgrade throughout our network and service.But not long after the upgrade (or maybe ever since the upgrade, we can't confirm this because we probably missed it out due to many other links to be tested), we met a peculiar problem.Everything seems to be running fine most of the time, but there has been some weird 'ghost-like' activity which have been causing inconsistent network disruptions. At times, certain portions of the network can't communicate with other subnets.And most obviously is the problem with a continuous ping and a traceroute simultaneously. Ping is usually normal, but until a traceroute is attempted, it times out at the same time as tracert fails to obtain the route.Besides, performing a ping from the 2nd closest hop address, 10.250.253.251, which is a cisco layer 3 switch also has problems, the results shown are as belowType escape sequence to abort[CODE]
View 1 Replies View RelatedI've got an annoying problem with my ASA 5520.I have traffic going from the inside interface (security level 100) to the outside interface (security level 0) with a global PAT applied to the outside interface address for all inside traffic - and I can't seem to traceroute through the firewall.The ruleset is simple - basically, allow any IP from inside to outside. The NAT is simple - PAT all traffic unless exempted to the IP address of the outside interface.If I do the trace from my internet edge router it works fine - so I know it's not soemthing my uplinks are filtering - but if I do it through the firewall, I get perfect responses until the hop where it hits the firewall interface - then nothing.Is there something I am missing that I need to do to allow traceroute to just work with all the rest of the traffic?
View 2 Replies View RelatedMy setup is :
Source--- Router 1 ( ip 1.1.1.1) --ACE---router---cloud---customer---router--destination( ip 99.99.99.99).
Traceroute from client to destination shows the following:
traceroute 99.99.99.99
traceroute to 99.99.99.99 (99.99.99.99), 30 hops max, 40 byte packets
1 1.1.1.1 (1.1.1.1) 1.10 ms 1.78 ms
2 99.99.99.99 (99.99.99.99) 1.01 ms 1.97 ms 2.511 ms
3 99.99.99.99 (99.99.99.99) 2.01 ms * 99.99.99.99 (99.99.99.99) 2.330 ms
[code]....
So on this, the destination is 99.99.99.99.The first hop is the default gateway, which is 1.1.1.1.After that, the next step is the Cisco ACE.After that there are several hops to the destination.Looks like for some reason the Cisco ACE is not recording his ip.( For any destination traceroute result is the saame.ICMP is allowed in the access list and also ther is ICMP inspect in my config. access-list ICMP line 10 extended permit icmp any
class-map type management match-any abc
201 match protocol ssh source-address X.X.0.0 x.x.0.0
class-map match-all ICMP_allow
2 match access-list ICMP
[code]....
Version running on ACE is Version A2(3.3)
there is an issue with tracroute from ASA 5505 with 9.0(2) - here is the running configuration [code] with this running configuration - from the LAN tracerouet to public IP, it is working fine. but once I traceroute from the LAN 192.168.225.x to the corporate networks via the IPSec l2l tunnel - it does not show any hop at all - even the inside interface of the ASA does not show in the traceroute.
View 4 Replies View RelatedWe have a ASA 5505 and a 5510, that we are using site to site..I need to traceroute from the 5505-5510.. From the outside interfaces.. Don't want to do this through the site-to-site.I have temporarily added a few acl on the outside interfaces..
-access-list outside_in extended permit icmp any any unreachable
-access-list outside_in extended permit icmp any any time-exceeded
-access-list outside_in extended permit icmp any any echo-reply
when i traceroute it only goes one hop.. Maybe thats the way it suppose to be? I need to know all the hops between the outside interfaces on the 5505 to the outside interface on the 5510.
I've read through netpro and found everyone points to this doc.

However that still doesnt allow traceroute through for us. We still see syslogs with deny's on high level random UDP ports to different Internet destinations.

I have configured a vlan interface on a 3750 switch. there is aprox 4Mb active traffic flowing through the interface, but when I do a "show interface vlan (vlanid)" the output show zero bits in and zero bits out. Its a typical L3 config with one IP on the vllan interface acting as the gateway for the VLAN devices. Is this a normal behaviur ? and if so is there any way to get the traffic in/out stats. The end PC/devices are connected to this switch via an L2 TRUNK and I dont have access to the L2 switch on which the actual devices connect. so cant get the real time stats of those interfaces.

View 2 Replies View RelatedJust planning my move to 8.4(2) and I'm looking for some input. In the past, I have a text file with name commands for every host on my network that I know about. I would then deploy this list to all ASAs so that I could create ACLs on any firewall using a name, which would correlate to the same IP on any firewall.Now, the names from the name command no longer work as a host entry in ACLs, therefore I'm required to switch all of my active name command entries over to objects.My question is, have any of you found an easy way to change all name commands to objects? Since the name command doesn't specify the mask of the entry, I think this may not be possible without manually updating thousands of records. I know that once I migrate, there will be some objects auto-created, but those will only be host and or networks which have NATs associated with them.
