Cisco Routers :: Using RV042 As Layer 3 Clear Gateway For Comcast EDI
Feb 18, 2013
Comcast installed a new fiber 10M EDI internet connection in our facility the other day and found out it is our responsibility to provide a layer 3 gateway to map the internet connection to the 14 public IP addresses they assigned to us. We are using RV042 for our existing networks with a T1 we had.
Will the RV042 provide the gateway function to route the single IP address comcast provided to the 15 public IP addresses? If so , can you provide the configuration example on this process?
Comcast EDI Connection ---> ???????? ----> 14 Static External Addresses

I have two Cisco RV042 Routers, they are being used to connect two offices, i have created a standard gateway to gateway connection, fixed public ip addresses on both sides and everything works fine, except when the tunnel gets disconnected, it does not connect back automatically, i have to log into either router console and click the connect button to get the tunnel working again, this is really annoying since it happens once or twice a day at least.

I spoke with the Comcast gateway support team and they changed my SMC router to the straight gateway/bridge option. If I plug directly from my laptop to the SMC, I have internet connectivity. So I know that aspect is working. I have a Cisco RV220W router that I want to be between the internet/SMC gateway and my network. For the life of me, I cannot get the internet connectivity to pass through to the router. I've done the proper power on order numerous times. Tried variations just for the heck of it. And nothing. Am I missing a step? If I do the "wizard" on the router, it basically tells me it sees no gateway even available even though it is clearly there and plugged into the WAN port. I don't see any option in the router settings for me to specify like the DHCP server I should be reaching out (if there even is one). My understanding is I shouldn't need to as the router should just recognize it. Should I be using a static IP instead?

We use a phone system that requires SIP Application Layer Gateway to be disabled on the router. We replaced the older RVO42 routers with the WRVS4400N routers and the VOIP phone works fine with this check mark option disabled.
Does the new RVO42 router allow you to disable this option? I did not find it in the manual so far. I do not want to buy two routers and find that it will not work with the phone system. We need Dual WAN this time so I thought we would try RVO42 model again as long as it is the latest version. Any issues with newer RV042, RVO82 with NEC VOIP phone systems?

I've got half a dozen RV042 routers in various locations. They are running v4.0.0.07. Seemingly randomly, I got the 502 Bad GatewayThe CGI was not CGI/1.1 compliant. error when attempting to log into the web interface with google chrome (same with IE too). This happens from the LAN side. I actually didn't notice it until my Opsview monitoring software threw up a critical when it didn't get an http response. The router is otherwise actually working just fine.Since the first occurrence, more of my routers have developed the same error.
I've tried different browsers, clearing caches, though I'm not surprised those efforts were fruitless, as there is clearly a problem even when no browser is involved (nagios). The nagios http check also returns a 502 Bad Gateway.

I set up an RV042 as a VPN gateway for a client a year ago. It is running firmware 1.3.12.19-tm (Feb 13 2009 13:03:21). I created a new certificate. When I download the client certificate, It comes as a .zip file. One the can not be opened by a zip utlity (windows, Winzip or 7 zip). It looks like I can just rename the file to a .pem file, but I want to make sure that is right. They were getting QuickVPN timeouts, but that looks like it was fixed in 1.3.13.

I have RV042 on my remote network, i have problems with VPN connection , user can connect to RV042 but only inside IPs that can ping from vpn user.Is it any way to make the traffic from Rv042 will back to RV042 . maybe with nat.. in example below 192.168.5.100 is my lan IP from my DSL dhcp, and 172.27.0.20 ip on remote, traffic not back to my pc/vpn client, what i want is to translate 192.168.5.100 to RV042 LAN ip address
1485: ICMP echo request (len 32 id 256 seq 29) 192.168.5.100 > 172.27.0.20
1486: ICMP echo reply (len 32 id 256 seq 29) 172.27.0.9 > 192.168.5.100
1487: ICMP echo request (len 32 id 256 seq 30) 192.168.5.100 > 172.27.0.20
1488: ICMP echo reply (len 32 id 256 seq 30) 172.27.0.9 > 192.168.5.100

I have router Linksys RV042 v1.2 with latest firmware Version: 1.3.13.02-tm. And I'm using QuickVPN v 1.4.1.2. I've setup VPN connection with values, below: But every time I'm trying to connect to router by VPN it always popup a window "Remote Gateway not responding".It occurs when I'm trying to connect to VPN behind other router, when I'm connected directly to Internet the connection is established.But I'm connecting to other networks using VPN and it's working properly (behind the same router), so I think it's problem with RV042 configuration but I don't now weher.

I am trying to setup the following. We have an RV042 Router and are using it as our gateway at the office. In the office we are using a Windows Domain abc.lan with DHCP of 10.0.0 - 10.0.0.254. The Router/Gateway is setup with a Static IP of 10.0.0.100.A couple of our office employees would like to work from home via VPN using their laptops. With the many options available for this router, I am not clear as to which options and what settings I should set.

I am setting up a dual WAN network in our small business office and I am confussed on the set up of the RV042.
On WAN1 I have a satellite modem connected
On WAN2 I have a cradlepoint CTR35 Router with a verizon aircard
The satellite has lag issues and will drop out during poor weather but has a 17GB dowload limit. The verizon aircard has only 5GB download limit but normally works in poor weather. Code...
Do I select obtain DNS automatically on both WAN1 and 2? Do I set this up as a gateway or a router?

I'm trying to set up a RV042 to do the following:
1) Block all WAN connections, except for:
2) Allow all port 80 connections, and forward to 10.4.20.60
3) Allow all port 443 connections, and forward to 10.4.20.60
4) Allow port 22 connections from specific IP addresses, and forward to 10.4.20.60
5) After a remote client has connected using Client to Gateway VPN, allow that remote client to access anything on the LAN
I'm able to do #1-4 above, but I can't get #5 to work. Or I can get #5 to work, but can't implement the restrictions I need in #1-4. Attached are some relevant screenshots. I think the problem is that I have Forwarding rules set up that require me to have a firewall rule to Deny All Traffic from WAN1 (unless I'm specifically allowing it). In the Access Rules screenshot, rule #6 is the problem. If I enable it (thereby denying all WAN1 traffic), then VPN clinents can't access anything on the LAN. However if disable this rule, VPN clinents can access anything on the LAN, but the firewall also opens up all outside connections to SSH, since that's set up in the Forwarding rules. I would have thought that once a remote client is connected using client to gateway VPN, then that client is considered to be on the LAN, as far as the firewall is concerned. Thus a firewall rule (like #6) that is specified for WAN1 shouldn't effect remote VPN clients.

I am setting up remote access using an RV042 router. Using quickvpn or a client-to gateway vpn and shrewsoft client, I can only access/ping the LAN side of the remote router and one machine on the remote network. The PPTP server and native Windows 7 connection provide access to all machines on the remote network.I have 2 possible reasons for this and would like to find the real reason:
1) The remote RV042 is behind another router, and that router restricts access other than the PPTP traffic.
2) The VPN tunnels other than PPTP only allow access to the remote LAN side of the router and remote machines that have the remote router defined as their gateway in the IP configuration.

I have a RV042 router. The problem that I am having with it is that the DHCP is giving out the wrong Default Gateway and DNS Server. There is no option to change the DHCP server IP on any of the settings pages on the router. I am begining to think that there might not be a way to do it. I see that there is an option for the DNS under the DHCP page but the Public IP that is being handed out is not the one on that page. I also have 2 WAN connections hooked up as well a DSL link and a Cable link (the cable link is the primary one).
The following information is provided in an effort to resolve this issue:
IP of Router 10.0.0.2
IP of DHCP Server (the one that is being handed out):10.0.0.1
IP of DNS (the one that is being handed out): 10.0.0.11
What I want to it be.
IP of Router: 10.0.0.2
IP of DHCP 10.0.0.2
IP of DNS 10.0.0.2

I have a 'Comcast Business Gateway' a friend gave me and I would like to use it instead of the regular gateway. The business gateway has extra Ethernet ports on the back where as the regular gateway just has one for your router. I plugged in the business gateway and I couldn't access the network. I used 10.1.10.1 which I thought was comcast's default but to no avail. I am not a tech so I am now stuck.The whole reason I am trying to do this is because the wireless routor is in the house, with a ethernet wire running to the shop. This distance is about 60 feet. I have the computer pluged into the wire but I can't get the printer or the other computer to connect to the wireless. I would like to connect the Business Gateway to the house wireless and then run the hard wire to the shop and connect another wireless router to the wire and run the shop on its own wireless. I tried one of the wireless extenders and it does not have enough juice.

Just got a never used AT+T Wireless Router (2701HG-B Gateway) from a friend to use with my laptop and comcast broadband connection. I have windows vista, and use IE as my main browser. Can I used, or is it set up to only work with an AT+T connection? I do have all the software discs that came with the unit, but haven't run them as they seem mainly for setting up DSL connection with AT+T.

I bought this wonderful voice gateway off the internet from someone. So not sure if they ever used it with Comcast.So far I hatve had no internet once I plug it to the cable. I have asked Comcast tech for activating this device. However they say it is not supported and they have tried sending it the Activation signal but they say it fails. I can see all lights lit up and go green when I connect this device to the cable, is there a firmware upgrade for DPQ3925 ?

I am setting up a e4200 wireless router on a Comcast business account that uses a gateway (SMC8014).I have fixed public IP [x.x.x.x/30] and the gateway sets up a subnet 10.1.10.0 (255.255.255.0). I have mail server and DNS server at 10.1.10.20 and I use port forwarding in the SMC gateway.
The setup of the e4200 using the software sets up a network (192.168.1.1). I can connect devices to the router and browse the external Internet. However, when my android phone connects to the e4200 it gets an IP such as 192.168.1.101. However, I cannot download my mail which is at 10.1.10.20. When I try to browse that IP from the android phone I get the SMC gateway at 10.1.10.1 and not the computer at 10.1.10.20. If was coming in from the external Internet port forwarding would take over but it does not work for the android phone connected to the e4200.
Also, i noticed that when I set up the default setup for the e4200 the "Cisco Connect" says the WAN address is 10.1.10.155 and the LAN address is 192.168.1.1. However, when I go to the SMC Gateway and list the connected computers it doesn't see the e4200 at 10.1.10.155. If I set up the e4200 within 10.1.10.0 then the SMC sees it (but the computer name always says "unknown"). It I set the DHCP in either the SMC or the e4200 within the 10.1.10.0 subnet I can see the phone connection in the SMC when I list the connections but any requests to 10,1,10.0 computers goes to the SMC gateway.

I was able to install the RV042 router to my ATT DSL line (WAN1 port-INTERNET) and it gets an external IP address automatically and the Internet works. When I connect my Comcast Internet to WAN2 port INTERNTE/DMZ) it doesn't get an IP address. and the Internet goes down and the WAN2 port ip address says 0.0.0.0.I've tried releasing/ renewing and it still says 0.0.0.0.Everything else is set as the default.

I'm building the below network configuration:
WAN -------- ASA5505 ------<802.1q trunk>----- L3 switch -----<802.1q trunk>----- L2 switch w/ VLAN support
The following VLANs exist on the ASA and both switches: VLAN 10 (10.10.10.0/24), VLAN 11 (10.10.11.0/24), and VLAN 99 (10.10.99.0/24).
The ASA5505 performs the following functions: routing to/from the WAN, firewall, NAT, and DHCP for each VLAN. It has an interface on each VLAN (10.10.x.2) for a DHCP server.
The L3 switch provides inter-VLAN routing and layer 2 switching. The L2 switch provides layer 2 switching, with VLAN support.
What should the default gateway on the L3 switch be? Should I set the IP of the physical interface connected the L3 switch to the ASA5505.

4500 config
Vlan 10

It has ip helper configured that points to DHCP.From 4500 switch port - port x connects to 2960 port.Port x is configured as trunk between 4500 and 2960.

All user ports are configured under vlan 10 and as access ports.Port x is trunk port connected frpm 2960 to 4500 switch allowing vlan 1 and 10 only.This switch has no default gateway configured.
We connected user PC on 2960 switchports and they were able to get the IP from DHCP server and were able to access the network? My question is how users on 2960 switch are able to access the network without ip default-gateway configured on 2960 switch?

I've got two RV082's connected. Each has a dynamic IP (changes typically every few weeks). I've configured the tunnels on both ends with a local and remote "Remote/Local Security Gateway Type" of "Dynamic IP + Domain Name(FQDN) Authentication".If I look at the VPN Summary tunnel status, it shows an IP address of "mydomain.dyndns.org 0.0.0.0" under the "Remote Gateway" column heading. The Tunnel Test "Connect" button is N/A.I can resolve both of the mydomain.dyndns.org entries on both sides of each VPN using the Diagnostic DNS lookup tool within each router. If I hardwire a fixed IP address for the Local and Remote Gateway everything works just fine. VPN is good.
I just can't seem to get the "mydomain.dyndns.org" function to work. It appears the router can't resolve the dynamic IP from the domain names on each of the routers.

I replace our aging rv082 routers with wireless rv220w routers. The gateway to gateway vpn works great, however I am no longer able to manage our print servers port 80 management page. I can ping any host with success, and I can manage hosts that have a port 10000 or 8000 web interface - but no port 80 ones... I had no issues when using the old rv082 routers...

I picked up a pair of RV220W's and before I spent loads of time at a remote site, I figured I'd go through some VPN testing at home to make sure I could get it setup properly. What this means is I've plugged the Internet uplink into a switch, then from the switch into both routers & configured them (using unique static IP's for each) from there. For what its worth: While I have some IT experience, I don't have strong networking experience.
I setup several VLAN's on the local RV220W, and the end result is to make it so that an asset at the remote site with an IP in any of the ranges (192.168.121.0/24, 192.168.131.0/24, 192.168.141.0/24 and any future VLANs) can communicate with/access resouces at the local site. Likewise, an asset at the local site with an IP in any of the ranges (.121, .131, .141 + any future VLANs) should be able to reach the remote resources (currently just 192.168.181.0/24, but future VLANs as well).
This evening I tried to focus on the relevant VPN pages of the Administration Guide to get the VPN up. Leaving the defaults I got as far as establishing a link between both sites and it seems that things are working right: From the remote site (.181) I can access the local site (.121, .131, .141); and from the local site I can at least ping resources (a laptop) on the remote site. (Yay!)
However, when I physically connected an asset that had a 192.168.121.X, 192.168.131.X and 192.168.141.X IP addresses to the remote RV220W (which is 192.168.181.0/24), I couldn't see it from the remote or local sites.I assume this is expected. But I'm reaching out to the community to see what other possibilities might be available becuase networking is a weak area for me. I figured it might be something like a Static [or Dynamic] Route but I really am not 100% sure.
'TECHNICAL' SPECS
Local Router LAN/WAN Settings:
LAN IP: 192.168.121.1 on default VLAN (1)
VLAN 13 defined 192.168.131.1 with DHCP enabled; Reservations created outside of DHCP scope

I'm running Cisco QuickVPN on a clients laptop (Windows 7). Windows firewall is disabled because McAfee SaaS is running.I sometimes have the issue that the initial connection attempt comes back with "Gateway not respoding" during the network verification process. You close the program, you open it again and it works. Sometimes it takes 2 or 3 tries. Today I have the issue that my client tried it like 20 times including several reboots and it's just not working. I tried it from my own computer and it connected fine on the 2nd try.I'm thinking that it might be time-out thing, that the VPN client doesn't receive a response fast enough? I know my clients home internet is darn slow.

I have successfully connected two RV042s to establish a VPN gateway to VPN gateway connection. I have the follow questions:
1. I would like to keep the VPN tunnel connection time indefinite. Is it sufficient by checking the "Keep-Alive" box on the VPN -> Gateway To Gateway -> Advance page? Or, I have to ping the RV042 periodically?
2. Do the "Phase 1/Phase 2 SA Life Time" (on VPN -> Gateway To Gateway page) settings have any impact on keeping the VPN connection time indefinite? What are the optimal values for them?
3. Is there an API, command, or script to replace a manual clicking on the "CONNECT" button to establish the VPN tunnel from the VPN -> Summary page? Or, is there a way to accomplish this at power up?
4. Is there a way to establish a VPN tunnel without going through login and clicking the "CONNECT" button? (Auto connect at power up?)
