Cisco Routers :: RV110W Blocks All Inbound Traffic
May 28, 2013
CE IP - 172.18.10.10 /30PE IP - 172.18.10.9/30 I had configured some floating static route on the PE towards CE .The routes were installed correctly till PE - CE link was UP as next hop IP was showing as connected .Now the link has been removed and I am receiving a supernet of 172.16.0.0/12 from PE2 via MPBGP. Although the 1st static route for 10.10.0.0 is showing in routing table, the other 2 ( 172.17.0.0 & 172.24.0.0 ) donot show. I believe that as both the routes and next hop fall under the supernet , the static route is not installing. But I don't know why is this behaviour. I tried to remove the distance 250 from both the routes , but still the static route does not install. I tried this on GNS3 but got the same results .

I have a RV110W that's been in service since Dec 2012. All Everything is working fine except every month or so the firewall starts blocking all inbound traffic. It does not respond to remote management access. If I reboot the firewall (pwr off/on) everything works correctly for the next month or so and then it begins blocking all inbound traffic again. Local access to the Internet and VPN tunneling are not affected. When it's working, all my rules and port forwarding work correctly.

I have a sip gateway connect to the LAN side of RV180 router which has ALG enabled. I have no problem to make and receive calls but sometime I see the router does not forward the 'Bye' message from the VOIP service provider to the sip gateway.
[Code]....
In the capture frame 4292, a 'Bye' message reaches the WAN of RV180 but it never forward the 'Bye' to the sip gateway with internal ip. All settings in RV180 are default with only ALG enabled. I tried to setup Access Rule or Port Forward but none seems to work. Not sure if they are over-ruled by ALG? With ALG enabled, is it possible to have individual Access Rule? If there are conflicts between ALG and Access Rule, which has higher priority?

I saw a reference to release notes for firmware 1.1.0.9 (I think that was the number) for the RV110W but if I browse the firmware download page I only see 1.0.1.6 available for download. Is this available somewhere or am I confused and saw a reference to something else?
I have an installed RV110W at a client site that has to be rebooted about once a week since it stops allowing inbound access to mapped ports. For example, it stops forwarding connections on Port 25 to the client's e-mail server. I thought for a while there was a software issue with the e-mail server but after days of eliminating all other likely issues I rebooted the router and everything was fine. Now the problem recurs about once a week and rebooting the router always fixes it (this is week 3). Forwarding to ports 80, 443, and several others also stop working.

We have a VOIP system from AT&T with T1 internet access. I have a RV042 setup as the default gateway for the network and the router randomly (usually over the weekend loses the internet). I have updated to the latest firmware and have check all logs on the server. When the internet access goes down we can still access the internal network. I have been power-cycling the router and then everything works fine. Is there a known issue with this router radomly blocking internet access in or out? This device should remain working at all times so that our remote users can access the company network.

I am using a RV110W as a VPN client to establish a VPN conection since some months. So far everything works fine. But all traffic is routet thru the VPN tunnel. Now I try only to route specific adresses thru the tunnel but not the internet acess.
RV110W is in Gateway mode
WAN interface is connected with internet
I am using PPTP with PAP and MPPE for VPN
so far no static routes (I could not set e.g. a route to 0.0.0.0 because web-interface says its not a valid adress)
Goal is to route only traffic for the target network thru tunnel and the rest direct via WAN interface.

We have a Cisco 2811 running ITP IOS. On that router we run the SMPP service. A client on the network connects to this service, and we need to capture the traffic for debug.
I've tried traffic-export, but I cannot see any outbound traffic.I'm guessing that this is due to the fact that the outbound SMPP traffic is not transit traffic as it is generated by the router itself.
Is there any way to capture the outbound traffic?

In our company we use ASA 5550 as a VPN server (failover pair, FW 8.2(5)). Long time we used Cisco VPN client (easyVPN) only and some time ago we started to use L2TP/IPsec VPN from Windows clients.From this time we can see strange behavior. Some ip addreses (we use ipv4 only) from local VPN ip pool are getting unusable for clients. When client gets this ip address the traffic from client to intranet is ok but the traffic from intranet to the client is blocked. This behavior affect both L2TP/IPsec and easyVPN clients with this ip address.The packet trace shows that the traffic will be blocked because implicit deny ACL but ACL for the connected user is created:
Phase: 10
Type: ACCESS-LIST
Subtype: vpn-user
Result: DROP
Config:
Additional Information:
[code].....
We use RADIUS for authentication and ACL. Failover to the standby ASA solves the problem but this terminates all L2TP/IPsec VPN connections.We use Cisco Anyconnect VPN too and when Anyconnect client gets this „strange“ ip address he can communicate normally without problems. It looks like that this problem is related to IPsec. how to discover why ASA uses -implicit deny- instead of user ACL?

I have a remote office with a 1.54mb circuit connected to our private MPLS network. Our main office has a 20mb conneciton to said network. I want to set a QoS policy for traffic from the remote office to our Avaya subnet within the main office. This policy is to give priority to all traffic to the Avaya G350.
I have set up the outbound traffic policy on our remote office router using a policy map as follows:
access-list 101 permit ip any 192.168.0.0 0.0.255.255 (this represents the Avaya subnet)
class-map match-all voice_outbound
match access-group 101
policy-map voip_outbound
class voice_outbound
priority percent 50
interface Serial0/3/0
service-policy output voip_outbound
This works fine for outbound traffic. Now how do I give priority to inbound traffic from the 192.168.0.0 network? When I try to do similar command it says CBWFQ is only configurable as output, not input.
I'd just limit it at the far end, but that has a 20mb pipe. All other traffic from our corporate datacenter, as well as internet traffic, flows from the main office to the remote office. Should I just rate limit everything else destined for the remote office subnet, and if so, what's the best method?

I have two Cisco 7606 routers using BGP to connect our customers to the internet. Recently we added a new 1G circuit in addition to an existing 1G circuit and all traffic inbound is now on this new 1G circuit. We would like to shift some of the inbound traffic over to the other 7606. Our Tier provider has the same AS number for both paths. One path goes directly to New York and the other goes to Boston then New York.

I have a working L2L between two locations. Location A and Location B.
Location A: 172.16.16.0/24
Location B: 192.168.0.0/24
I would like to block anything inbound to Location A from Location B that isn't initiated from Location A. The block should be done on the ASA5505 at Location A. Location B uses an ISR G2 router. i.e. Location A can start an SSH session to a server in Location B Location B cannot start an SSH session to a server in Location. .
I tried using a VPN filter on the ASA5505 but it isn't stateful, I cannot pass any traffic when using it.
Config on my ASA:
access-list vpn-traffic extended permit ip 172.16.16.0 255.255.255.0 192.168.0.0 255.255.255.0
access-list block-vpn-to-local extended deny ip 192.168.0.0 255.255.255.0 172.16.16.0
[Code]....
I also have an AnyConnect VPN setup for the ASA5505 and it is running 8.2(5).

I use a mail filtering service that delivers mail to me via SMTP on standard port 25 on one of my 5 static external IP's. I wish to restrict this to their IP's only (they have two) and I am unsure on how to do so? As it stands now, anything on the net can talk to my mailserver and my logs are filling quickly with failed attempts as a result. Here's my setup and what I am trying to accomplish:
mail filtering service -> my public ip:25 -> internal mailserver at 10.0.10.2:25, deny everything inbound except traffic from the mail filtering service, I am thinking an ACL would fit the bill here, but unsure of how to implement. Router is an 1811 with version 15.1(4)M3 IOS. WAN is on fa0, lan is on fa1.

We have a L2L VPN with a vendor and our outbound traffic (our local network is 192.168.0.0) NATs over one of our public IP addresses x.x.x.164 to their public IP address 128.x.x.x. In the beginning all our traffic was outbound (port 23) to the vendor and now we need to allow inbound from the vendor to specific 192.168 addresses on our network using port 9100. I’m uncertain as to what I should do to allow their inbound traffic to these IP addresses since we are NATing our entire network over one IP address. Note, the .164 public IP is also used to NAT to other vendors we have L2L VPN with. The VPN terminates to our ASA 5580 version 8.2.

I have an ASA5510 with 8.3 and a Cisco PIX525 (retiring). The ASA was for VPN traffic only while the PIX was for all other Internet traffic. I'm trying to move all the traffic to the ASA5510 so I used the PIX to ASA migration tool. I migrated the PIX rules over to the ASA5510, however we can't receive email and there is no external access to our internal websites. But the VPN connections remain intact and internal users can get out to the internet.
When I run Packet Tracer on my outside (incoming rules) the packets are dropped at the inside interface. What am I missing?

We want design a topology based on transparent proxies using WCCP. Our proxies can do spoofing of user ip addresses. So, the HTTP request will go out our network with the user ip address as source ip. The HTTP Response will arrive with destination address the user ip address. We want use WCCP to redirect inbound and outbound traffic because we have c3750 with L2 WCCP support. The outbound redirection, when the packet is going out our network is simple. But, the problem is the inbound redirection. How we redirect this packets to proxies by WCCP?. Is it possible?. This redirection is done by c3750 using TCAMs/hardware?. Our throughput could grow until 2-3Gbps and we are worried about the performance.

I have a client that has an ASA 5520 that has two internet connections, FIOS and Comcast. The ASA is configured to failover from the FIOS to the Comcast if the FIOS fails. This works perfectly fine. However, I was wondering if VPN and other inbound traffic will come into the secondary connection when it is active. I think VPN will work inbound when the FIOS connection fails, but I am not sure about the other inbound connections.

I have a VPN on my ASA 5510 between (A)192.168.255.0/24 and (B)172.20.2.0./24. The purpose of the tunnel is to send kerberos tickets from our domian controller on the A side, across to a server at B, and receive a respose. I want to lock down inbound traffic to the A network, but not sure of best method.
I initially tried using an ACL filtering on ports, but soon realised the incoming traffic uses a wide range of ports so this is not really possible.Seeing as the A side will always be initiating the conversation, I was wondering if I could use the 'established' option on the inbound ACL for the ASA at A side, so that it would block any flows that are not initiated by the A side.

I have been trying to figure out a NAT issue on my 2811 and the inspect engine.I have 'ip inspect FW out' on my outside interface. If I turn it off, I also have to remove the access-list applying to inbound traffic on that same interface. Why is that? This whole thing centered around SIP registrations from devices on my LAN to my provider. The provieder is showing that I am registering from a high end port (1024 or something crazy). He said that it sounds like some type of SIP ALG or something on my router. For the life of me, I can't figure out what would be causing it. I am just using a standard route-map that points to the outside interface using 'overload'.

We are using Cisco 3750 switches in our environment as distribution switches.We currently use to police inbound traffic, but we need to find a solution to limit inbound traffic per IP.Something like this “Inbound traffic for each IP can be maximum 1 Mbps” This can be done having, one ACL and one class-map for each IP, but in my situation is not a practical solution, because we have more than 500 IP’s on that site.
Is any way to accomplish this without writing 500 ACLs and 500 class-map?

anything I put into my hosts file, will not go through the Cisco RV220W router. This is part of the set up:
192.168.1.10 << RV220W
192.168.1. 15 << A client machine
192.168.1.99 << Internal DNS with forwarder to OpenDNS (208.67.222.222 & 208.67.220.220) + a laptop that's not on the internal network at all.
Now, the client machine and the laptop both have an entry in their hosts files:
174.156.12.81 insight.hello.com
From the laptop, I can both browse to insight.hello.com, and I can ping it in Xterm.
From the client machine (192.168.1.15) which is behind the Cisco Router/FW, I can ping insight.hello.com, but I can not browse to it. This is especially strange since the ping goes through the Router every bit as much as the http traffic does, so why is the router giving me a DNS error on that, but the ping goes through just fine?
The hosts file is supposed to supercede any other information from anywhere, so it out to not be a problem for the router either. Yet, it obviously is.
I have tried to disable the internal DNS server as well as OpenDNS and just run the ISP's DNS servers, but no change - I still get that blue DNS error screen from the CIsco router.
Above IP's & hosts are fictitious.
The hosts file doesn't get blocked in a sense, but what happens is that if you have "Content Filtering" checked - even without any rules - the router can not verify that 174.156.12.81 is in fact insight.hello.com in this case, since it doesn't exist in the public DNS system.
So, I unchecked Content Filtering and now it works as it should.

let me know whether you can make the attached network using by RV110W or not.When I read the mannual of "rv110w_admin.pdf", P38, I guess RV110W cannot be built both NAT & Router mode.Because, I cannot setup NAT for internet access if I setup "Operating Mode" as "Router" on the setting of "Networking > Routing".And, I cannot setup the routing for internet access & MPLS-VPN access if I setup "Operating Mode" as "Gateway" on the setting of "Networking > Routing".

Is it possible to set up an RV110W to limit access to only specified websites according to a schedule? I can block access to specific sites using the Internet Access Policy settings under Firewall, but I can't figure out a successful way to block access to all sites except those specified. I also tried establishing access rules but that did not work either.

After nothing but hassles with my Linksys WAG120N, I bought a Cisco RV110W. Yesterday, I tried setting it up with the Linksys being used only as a modem. I was unable to though because when I entered 192.168.1.1 into my browser as per the Cisco setup instructions, I was taken to the admin login for the Linksys. This seemed odd to me, because the Linksys was not connected to the PC at all. The connection setup was exactly as specified in the RV110W instructions: modem connected to dsl line, ethernet cable from modem (Linksys WAG120N) to the slot marked "WAN" on the RV110W, another ethernet cable from RV110W to my PC. Despite this, the admin page was for the linksys not the cisco.
Today, I exchanged the WAG120N for a Netgear DM111P, just a modem, not a router. Same setup configuration: modem connected to dsl line, ethernet cable from modem (NetgearDM111P) to the slot marked "WAN" on the RV110W, another ethernet cable from RV110W to my PC. Same result - type in 192.168.1.1 and get taken to the admin page for "Netgear DM111P" .

I'm having problems setting up VLANs on my RV110W Small Business Router. I have updated the firmware to the latest : 1.1.0.9 Here is my set up :
WAN settings :
IP : 192.168.1.252 / 255.255.255.0 - Gateway 192.168.1.254
VLAN1 (default) :
IP : 192.168.2.254 / 255.255.255.0
VLAN3 (test) :
IP : 192.168.16.254 / 255.255.255.0
Inter-VLAN routing option is checked.
Symptoms :
- The communication from VLAN1 to WAN is fine
- The communication from VLAN3 to VLAN1 is fine
- The communication from VLAN1 to VLAN3 is not working
My routing table is :Routing table Entry ListDestination LAN IPSubnet MaskGatewayInterface192.168.2.0255.255.255.0192.168.2.254LAN192.168.1.0255.255.255.0192.168.1.252WAN192.168.16.0255.255.255.00.0.0.0LAN0.0.0.00.0.0.0192.168.1.254WAN
As you can see, the gateway for VLAN3 is set to 0.0.0.0, which is wrong I believe. I don't know how to update that. I tried to add a a static route for the subnet, but the router did not let me do that.

I am trying to configure wake on lan for my desktop and I can't seem to get it. I have tried using single port forwarding under the firewall settings but it never works. The computer's BIOS has been configured to wake on lan and so have the Ethernet ports. I have an app for the iPad that i used to use ot send out a ping to my old router (E2500) setup that used to wake the computer just fine. But this new router (RV110w) does not work at all even with the same single port forwarding set up.

I've to setup RV110W router as a simple Wifi hotspot in a company network and this Wifi hotspot has to allow traffic to all internal LAN (very simple LAN with few workstation and one server) and also to Internet via our gateway. I know this product isn't really designed for that... but I've to do so. LAN is managed by Windows DHCP server and I've Internet acces through Firewall. I think I've to connect RV110W to the company LAN with the RV110W WAN interface. I want the Wifi IP address to be in the same IP range than the LAN to allow Wifi clients to access our internal server but RV110W doesn't accept this. Or do I've to ignore the WAN interface and deal with only the RV110W LAN interface?
