Cisco :: Which Source IP Will Router Use For Outgoing ICMP

Jun 6, 2012

I have router which has two physical interfaces Gi0/0 and Gi0/1. G0/0 connects to metro over ethernet and Gi0/1 is configured a s router on a stick, which has many defined. All those interfaces have IP addresses assigned. EIGRP is configured between other metro sites. Here is a sample IP assigment for this site, let's say Site.

Cisco Firewall :: ASA 5510 / PAT / ICMP Echo Outgoing IP

Apr 16, 2013

I have ASA 5510 with soft version 8.4(5) installed. There are two interfaces:
 
IP 1.1.1.1/24 - inside
IP 2.2.2.1/24 - outside
 
I have configured PAT, so network 1.1.1.0/24 gets NATted to 2.2.2.2 address. Everything works fine, except I can't reach 2.2.2.2 via ICMP from the internet.
  
X.X.X.X 2.2.2.2 Deny inbound icmp src OUTSIDE:X.X.X.X dst OUTSIDE:2.2.2.2 (type 8, code 0)
 
But I have configured an access list allowing ICMP from any to any: access-list outside_access_in extended permit icmp any any
 
Thus address 2.2.2.1, which is binded to outside interface itself, is perfectly reachable via ICMP.
 
I've got two questions:

1) Is there a way to fix it? It will be handy for diagnostic purposes.

2) is it possible to configure the secondary IP address on the interface on ASA? I've read, that there are some complications.

Cisco :: 1900 Outgoing Email Doesn't Go Through Router

Jul 8, 2012

We have Cisco 1900 Series Integrated Services Routers (has a wired router and a wireless router) and since this morning we can not send emails.I inquired with both the ISP and the hosting provider and all settings are correct.I can receive emails from outside the router, but can't send any emails out.If I try to telnet mail902.opentransfer.com 25 it doesn't connect.Port 25 is the port we were using all the time and was working through the router.I connected my laptop directly to the modem and was able to send emails using port 25, also was able to telnet to outgoing mail server. I didn't change anything in the router.is there a way to "enable" port 25 or "enable" mail.homeserviceclub.com (smtp server) or mail902.opentransfer.com (hosting mail server) if this would solve the problem?I don't understand why is this happening as I never had to enable or disable any email ports or mail server addresses.

Linksys Wired Router :: BEFSR41 V4.3 Won't Log Incoming Nor Outgoing

Jul 15, 2010

I went a bought a brand new model V4.3. I had trouble installing it right from the word GO, but I did successfully get that acomplished, how ever one of the important features "logging of incoming and out going ip" won't work at all. I tried deleting the old logview.exe and rebooting  everything, then installed the "new" logviewer.exe. Well absolutely nothing happens. I have double and triple checked the setting in the router...logging is turned on,  the computer which has the logviewer.exe installed is the confirmed network ip i.e. 192.168.1.101 and I can and do access the internet and all other computers on the network from that computer.

Linksys Wireless Router :: Incoming / Outgoing Logging Broken On E2500 Firmware

Jun 20, 2012

Have a few of these routers internally as well as at various clients.  The incoming and outgoing logs show up blank, even when there are 10-20 computers using the Internet and I know there is traffic being generated.  DHCP and security logging still works fine.  I also have a few E1200s on the latest firmware that are logging just fine... I'm just having issues with the E2500s.

Cisco WAN :: NAT Rewrite Source Address 800 Series Router

Aug 23, 2011

I'm stuck with some NAT issues. I've got an 800-series router wich connects to the internet via a PPP connection (dialer0). On the inside the router has 192.168.0.253/24 as IP address, the outside is negotiated with the ISP
 
My mailserver has the ip address of 192.168.0.1 but with default gateway of 192.168.0.254 (primary internet connection). If I use plain NAT (ip nat inside source static tcp 192.168.0.1 25 interface Dialer0 80) the packets arriving on the mailserver do have a public  IP address as source address.

Would it be possible to rewrite those packets (source address) so they have 192.168.0.253 as source address. This way the mailserver won't send the replies to it's default gateway but back to the cisco router.

Linksys Wireless Router :: WRT45G - Possible To Allow ICMP Ping Response

Jul 13, 2008

I need to remotely monitor a WRT45G from a remote host on the Internet. As such, I want to allow ICMP ping replies on the public Internet interface. However, I have found no feature to allow me to do this. Similar Netgear devices do allow this feature. I suspect the answer is, "you can't do that".

Linksys Wireless Router :: E1500 / ISP Blocking ICMP On WAN Side

Oct 5, 2012

Device: Linksys E1500 - firmware: 1.0.01? I've got a static IP setup for a small remote office and want to keep tabs on their internet connection by pinging it via a monitoring program we use. However, the router seems to not responding to ICMP.

- Filter Anonymous Internet Requests is unchecked.- I've verified that the Static IP is correct.

- I've tried pinging from several remote locations on different connections, with no avail.
 
I can't seem to figure out why i can't ping this device. I just want to make sure there isn't a setting in the wireless router that is preventing echo replies.The only other thing i can assume is that Comcast is filtering ICMP on their side of the WAN connection.EDIT: Here's a traceroute from my PC to the WAN side of the Linksys....

Cisco WAN :: 2821 MS Group Policy Failure / ICMP Size Too Small On Router?

Nov 29, 2010

When you use Group Policy to determine whether a link is fast or slow, fast links may be incorrectly flagged as slow links.
 
This problem may occur when a network that you are trying to detect a slow link to is configured to control the size and flow of Internet Control Message Protocol (ICMP) packets. For example, if a router allows for only ICMP ping packets that have a size of 1,024 bytes, the slow-link detection feature may flag the connection as a slow link. This is because the router discards ICMP packets that are larger than 1,024 bytes. If the router discards the packet because it exceeds the allowed size, fast links may be reported as slow links.
 
According to Microsoft, the default ICMP ping packet size of 2048 is used.Microsoft recommends changing every single Windows machine's ICMP size...but my customer would rather just change the router. It is a 2821 router, running 12.4(24)T4, using MLPPP to bundle two T1s.

Linksys Wireless Router :: Download Source For E4200 V1.0.0 Firmware?

Aug 1, 2011

link to the original v1.0.0 firmware for the E4200.  That was the best firmware for me and sadly I can't find a link to go back.  v1.0.0 really had no problems for me.  I initially skipped v1.0.1 becuase it disabled IPv6 which is a feature I want.  v1.0.2 broke my YouTube and Netflix streaming.  So I went back to v1.0.1 and my Netflix and YouTubue steaming returned to normal but I lost IPv6.
 
Any solution to Netflix and YouTube streaming problem on v1.0.2 when IPv6 is configured.  (I'm positive the video is streaming over IPv4, but the IPv6 connectivity is available.)

Linksys Wired Router :: RV082 ICMP And HTTPS - Computers Only Can Navigate Through HTTP Web Pages?

Oct 21, 2012

Let's see if you can with this one:
 
DSL Internet Router (Dynamic IP) -> Linksys RV082 -> Firewall PC -> LAN
 
DSL Internet Router: 192.168.3.0/24
Linksys RV082 WAN2: 192.168.3.0/24
Linksys RV082 LAN: 192.168.5.0/24
Firewall (2 Nics): Nic1 is 192.168.5.0/24 and Nic2 is 192.168.1.0/24
LAN: 192.168.1.0/24
 
RV082 WAN 2: Configured with a DHCP IP Address from DSL Internet Router so it has 192.168.3.0/24 range IP.
Load Balancing enabled
Static Route added on RV082: 192.168.1.0 mask 255.255.255.0 gateway 192.168.5.x interface LAN
Firewall PC is completely Open as i was using it before.
 
I had a Fortgate 60B and everything worked fine, then a bought a RV082 and now i can get this up and running properly.The thing is this....whit the actual setup i have, computers only can navigate through HTTP web pages, other ports seem to be closed, but if the Firewall PC was blocking this i guess i'll know because it shows a message on screen when a policy is being applied. If i try to open HTTPS Pages it doesnt work, Even a simple pinng to google.com doesn't work from my LAN (192.168.1.0/24), but if i connect a computer on a local port on RV082 i can PING and i can browse anywere i want.
 
It seems to be that Firewall PC is causing problems but i execute a tracert to [url]...., the packet get stuck in the RV082.What im thinking is that maybe the RV082 doesn't allow to go trhu at all if the traffic comes from other networks that doesn't belong to the one configured on its LAN side.By the way the Firewall PC connected to the RV082 directly navigates perfectly.
 
PS. The reason im using Firewall PC is because that way is much easier and flexible to handle policies for Internal users than in the RV082 Router. I use this ume basically to set up VPN IPSEC and Dual WAN Load Balancing.

Cisco Firewall :: ASA 8.3 Outgoing NAT Not Working Right

Jul 11, 2011

We recently upgraded our ASA to 8.3, most everything went ok, but I am having problems with outgoing nat. It seems that when one our systems that needs to be natted to an outside IP address when connecting out is not doing it. When that system goes out the ip address is our internet IP and not the natted address, however, inbound everything works.
 
We have one rule that does PAT
 
nat (INSIDE,OUTSIDE) source dynamic OG_IP_NAT_DMZ obj-1.1.1.1This is the natting statement that should be translating the addressesobject network obj-10.200.0.10
nat (INSIDE,OUTSIDE) static 2.2.2.2I think I need to double nat, is that right if so how?

Cisco :: E1-CAS With E1 Controller On 2811 - No Outgoing Calls?

Nov 8, 2012

I have programmed two E1 ports on Cisco 2811, one for E1-PRI and other for CAS. My running-config is as below

controller E1 0/0/0
framing NO-CRC4
clock source internal
ds0-group 1 timeslots 1-15,17-30 type r2-digital dtmf dnis

[code]....

I have made 4 as trunk group access on the PBX for E1-PRI and 8 as trunk group access for E1-CAS.I am able to dial 4-1-6261 to place calls on telephone 6261 from 6000(outgoing and incoming over PRI). And I am able to dial 4-2-6261 to place calls on telephone 6261 from 6000(outgoing on PRI and incoming on CAS).But I am not able to dial out from my PBX extensions over the E1-CAS card using 8-1-xxxx or 8-2-xxxx. I have patched two PBXs back to back on their E1-CAS ports and am able to dial out using 8-xxxx. So this means the trunk group allocation on PBX is working fine. The show controller e1 0/0/0 is showing normal stats.When I do a show voice port 0/0/0:1 I see that one of the ds0 timeslots are being seized when I try to dial out on 8-x-xxxx but the Out Status column entry against the timeslot says clear_bak.When I am placing calls on PRI, I don't see any such indication against the timeslot being seized.Basically since I am able to dial in to my E1-CAS port, the line coding, framing, signaling(to some extent) must be right, or so I guess. But am not able to dial out.

Everything elase like internet.Other servers all working fine. Only problem is that when ever someone dials a landline number from an extension it does not go through.seems like the firewall is blocking it but I cannot figure out why or how. All the NAT and Access list is fine. Although I have no idea how to accept the SIP PROXY IP through the firewall and I am guessing that might be the problem.  There is no any other problem and I am 100% satisfied with the ASA5505 except this problem

Cisco LAN :: 2651XM / Traffic-export Only Shows Outgoing?

Oct 12, 2012

cisco 2651XM router with WIC1 adsl card and NM-16ESW switch
IOS:  c2600-ipbasek9-mz.124-23.bin
 
I use the following config to export traffic from the adsl card to a fasterthernet port so I can look at the adsl traffic in wireshark on a pc:router(config)#ip traffic-export profile my_rite router(conf-rite)#int FastEthernet 0/0 router(conf-rite)#bidirectional router(conf-rite)#mac-address abcd.efgh.ijkl (mac address of PC) router(conf-rite)#exit router(config)#int dialer0 router(config-if)#ip traffic-export apply my_rite this config works and I can see stuff going on in wireshark but it's only one way. This config only shows traffic going out from my adsl card, but no incoming. There is defintely traffic going both ways because everything about my adsl connection is working perfectly. I've tried using a different fastethernet port, even tried exporting to a different pc but all I see is outgoing ie: source is my public ip address but never as destination . I have bidirectional in the config but it still only shows outgoing. I even tried a different IOS (c2600-adventerprisek9-mz.124-15.T8.bin) but still it doesn't show incoming traffic. Could it be my ISP in some way hiding incoming traffic from view?

Cisco WAN :: 2960 - Block Outgoing Multicast On L2 Port?

Aug 2, 2012

is it possible to block outgonig multicast L2 frames on an Ethernet port in outgoing direction on a 2960 Switch?
 
I tried the "switchport block multicast" command, but the description of this feature relates to only "unknown" multicast!?
 
But what means "unknown multicast"? Even if activated, I see a lot of multicast traffic going out that port: IGMP, PIM, SSDP, HSRP, OSPF, .. and also pings and VLC streams to multicastaddresses (ip igmp snooping disabled).
 
I also tried to map a "mac access-list" to that port, but the "mac access-group" interface command is restricted to only incoming traffic.
 
Reason: we assume, that there are a couple of specific enddevices, that might react strange to some multicast. Therefor we would like to block outgoing multicast on that specific ports.
 
I tested it on a 2960 12.2(53)SE2

Cisco Routers :: WRVS4400N - VPN Tunnel Up But No Outgoing Traffic?

Jan 29, 2012

we've buyed a WRVS4400N to create a IPSEC VPN tunnel to our client in order to access some applications.
 
After a while trying to configure the router, we have archieved it and the VPN tunnel is up. We can see the tunnel up from here and from client's side as well.
 
Our client supposendly have created the tunnel in order to access a list of specific IPs in the range 10.113.x.x, but if we try to access this IPs via telnet whe cannot obtain any response.
 
Making a tracert, we obtain...
C:UsersHuexxx>tracert 10.113.56.177
Traza a 10.113.56.177 sobre caminos de 30 saltos como máximo.
1     1 ms     1 ms     1 ms  192.168.0.1
2     *        *        *     Tiempo de espera agotado para esta solicitud.
3     *        *     ^C
 
... and therefor the client doesn't receive any packet at its firewall.
 
I've tried to establish a static route for 10.0.0.0 255.0.0.0 to their remote gateway, but I'm unable to add any entry to static routing list... The router tries to do something, but afterall I cannot see the new entry...
 
What can I do to route the traffic through the tunnel?

Cisco Firewall :: ASA-5520 - Cannot Hear Outgoing Message

Dec 9, 2009

We have setup the IP phone proxy on our ASA-5520, we had a couple of issues with the initial setup, but nothing major. It has been up and running for a few weeks and basically everything works perfectly just like we designed it except for 1 strange audio issue on outbound calls. We can make a call to anywhere, no problem, if the call is answered, no problem, perfect call setup and good quality 2 way audio. But if the person we called doesn't answer the call and that call goes to their voicemail we loose all audio from that point forward, we do not hear their outgoing message or get any prompts just dead air. The same situation appears to be true for any "recorded" service on the other end of the call.

I had spent the afternoon updating all necessary programs where updates were available, did a GRC shieldsup test, did a clean and test of my system with AVG and MBAM. Everything looked fine.I went online that night however and as soon as I went to my online banking website, I noticed that there was an outgoing attempt logged in my firewall (ZoneAlarm). It was blocked. The IP address is 72.167.239.239:80 - which apparently fits in GoDaddy's IP range. Googled it and saw that someone else had the same issue.
