Cisco Routers :: RV042G Subnet Mask Drop-down Menu
Nov 27, 2012
after recovering from the PPPoE-port-forwarding-fiasco I had with the RV180 (url...), I decided to try again with a Small Business Router from Cisco. This time I took the RV042G, hoping that the higher age of this product comes with a more mature firmware.So far the functions I need, work satisfying. There is only one issue: The subnet-mask is only configurable using a dropdown-menu. I've read the posts from the Cisco-Support staff saying, that this is because it is only a SMB Router. So, we are a small business and we use the 172.20.x.y net for several reasons. One of it is to distinguish and group several network devices using the third block of the IP. Eg. our printers IPs start with 172.20.5.x and so on.
My question is: Is it really impossible to change the subnet-mask dropdown-menu to a simple text-field in the frontend? Because it is possible to change the subnet to whatever one needs by a little cURL-magic: [code] This sets the new subnet-mask permanently (even survives a reboot and is displayed correctly on the system-status page) and I have not discovered any problems.The only thing is, if you change settings on the setup -> network page, the netmask is reset and you have to rerun this script.

I want to use a subnet mask of 255.255.254.0. The setup window doesn't allow me to type in that mask, rather it only allows me to choose from options on a drop down menu (which doesn't include that mask). Is there a way to do this?

I have a RV042 with two ADSL services on it, that is a nice simple thing for this unit. The problem that I am having though is that one of the ADSL services also has a /29 attached to it.
How do you go about configuring this additional sub net? On a previous unit I have had to create IP aliases, and could then port forward and NAT without too many issues, but it doesn't appear that the RV unit seems to work the same way.

I have old interface hardware with Static IP 10.2.2.200 and on the same switch I have computers with IPs of 10.4.1.0 If I change subnet to 255.0.0.0 old hardware with 10.2.2.200 will be accessible. The problem is that I would like to have 255.255.255.0 as subnet but it should still be possible to access 10.2.2.200. Can I add Static route for oldhardware in XP without adding gateway settings? The most simple would be to put all on same subnet but it is not possible due to a various reasons. The computers are running Windows XP

I want to calculate Subnet Mask for 3 Router Each one in separate building the First building need 60 host and the second building 25 host and the last one 25 host .
Knowing that the company currently reserved public class C network address 210.2.1.0/24 for internal address and subnet 210.15.10.0/30 for the connection to the Internet router.

I understand ip addressing and what a subnet is.But why is it sometimes I connect two things together,it always requires a subnet mask, and other times no? For example when I try to connect two computers together, it requires both IP and subnet mask.But if I use FTP software all it ask for is IP.Same thing when connecting to a website through their ip, doesn't require subnet.

I'm using my WRT320N as a home router, I need more ipadresses to be delivered to my computers, yet I can't get my router to give med wider netmask range. In the list I get 255.255.255.0 - 255.255.255.240 or something like that. I need 255.0.0.0 on my network and that would be perfect if i could get that...

We have an ASA 5520, working fine.One of the interfaces is connected to users PCs and printers mainly. Last months the number of devices has grown rapidly, and we would like to make some changes in it in order for it to be able to host new devices.We thought on change subnet mask of actual subnet (10.0.2.0/24) to 10.0.2.0/23, so it can hold as many devices.I understand I have to make some changes in the ASA, but my question is:What will happend to the acces rules I have created?Will I need to create them again? There are some objects which carry information about subnet mask, so I suppose I will need to redefine them, but for those without any subnet mask information, will I have to redefine them?

We have 10 ADSL lines and 5 of them goes in the load balancer (One gateway) and the rests are used as default gateways for internet access. We use ADSL routers as access points for internet, but those routers should be part of our network and should be given an address in order for them to act as default gateways for internet access. I'm facing a real prob with the ADSL routers Linksys WAG54G2 because they doesn't support a subnet mask 255.255.0.0 Any recommendation for an ADSL router model that support a netmask 255.255.0.0 ?
My cisco 2811 router interface configuration ip address: 172.20.0.1 255.255.254.0.Load balancer output lan ip address: 172.20.0.5.My ADSL routers will be in the following range : 172.20.0.6 - 172.20.0.10

Have a problem with a laptop connecting to a Wireless Router. The laptop was working fine on the last router which was on an ADSL Network.. (not that that matters),When the new router (Virgin Media / Cable) was installed all other laptops where connecting to it without any probs, but not this one.The laptop in question still receives an IP address, Subnet mask and Gateway from the router - Vista says Local only, no internet access. It cannot ping anything else on the network either. When I do ping it comes back destination host unreachable.

I was looking for a small business router that has VPN support and dual WAN support for load balancing. Upon reading reviews, I think RV042/RV042G is a good choice. Now am thinking if it supports intervlan/ router-on-a-stick configuration?

I was configuring a new unit straight out of the box to test a configuration for a client. I got most of of the configuration done and was noticing the menus were quirky and so I check to firmware and discovered it was 1.1.16 (* down level).
I finished my setup and rebooted to complete the changes, when I went back to log into the console it would Actively refuses to connect . the first time after powering on it shows the page title as setup before failing
I have tried a hard reset ( 15 Seconds reset) but it does not work . it doesn't even reset the settings. (static IP etc still there)
how can I get it fixed / exchanged under warranty

Today I had to reset the router completely to factory default, if I was adding services to the forwarding or UpNp service management, suddenly it stopped adding the new ones.Now after starting all over it's having the same behaviour, see below my services, normally you can have 30 rules in this list but I cannot add new ones now.
Now I want to insert a new service IMAPS for port 993 so I go to service management.Then press "add to list" see below for result.It is there, then press OK and the screen closes, now if I choose a service from the list, it is not there !!

I am using a Belkin AC1000 DB Wifi Dual-band AC+ Gigabit Router with the Belkin Router Monitor on a Macbook Pro (mid 2012) running OS X 10.8.2. I recently installed the router and the Belkin Router Monitor and everything works very well. I have one concern, however: the menu button on the finder bar is not illuminated blue, as it should be, but gray.

I purchased RV042G and setup one-to-one NAT problem to several servers. ometimes the NAT servers lost the internet connection. My case as below
ISP provide two set Public IP Address , one modem
e.g.
set one) 100.100.1.2-6, gateway 100.100.1.1
set two) 200.200.2.2-6, gateway 200.200.2.1
[code]....
All computers and servers (one-to-one NAT) outbound and inbound all work fine. After several hours, only the servers (one-to-one NAT) alert internet connection broken, but the computers (non NAT) still have internet connection.
What's the problem occurs? Why only one-to-one NAT servers lost the connection? and Why only serveral hours later, the server lost the internet connection.
If I changed the WAN setting to same as subnet of the one-to-one NAT, it doesn't occur any problem.

I run my business network on the 192.168.x.x range with a server set as 192.168.2.4 statically. The router is currently connecetd to two DCHP wan connections from my ISP, I'm on a residential consumer plan. It has defaulted to loadblanacing with the second WAN however I want to have the second wan's public IP be used by my server and only the server however I wish for the server to still be on the lan so I can use HYPER-V's brided network connection feature to run VMs on the lan, and I would like their wan connection to be from wan 1... as for the entire lan except the server at 192.168.2.4 Is this possible, I can't seem to get the 1-to-1 NAT to do it?

I've setup the RV042G with one ISP connection for now.I have my main PC running fine, but I have another PC hard lined to the router that had a connection after I power cycled the modem and router but now it no longer does. disabled the network on that PC, now I can't get it back at all.I have a wireless e2000 in one of the ports that I disabled the DCHP on and it seems to be running nicely.before I disabled the PC in question, aka port 3, it was showing as connected in the "192...." but now only as enabled.

I have an issue with routing public IPs on the RV042G. I have been able to route the IP's in a couple of different ways, but there is always a nagging problem.
I have a PPPoE Business Class account with 5 routable public IP's. I would like to route the IPs and manage the private network using the RV042G.
Here is what I have tried and the problem that arose: 1) I used 1:1 NAT and the servers responded with no issue. This would be a workable config however I use Kerberos for single sign-on for my clients. To use this security protocol and bind the clients to the server, I must use a public IP on the server machines. In this scenario however, everything else worked fine. 2) I then tried using the DMZ and putting the servers on the DMZ port with a public IP entered in the network config of the machine. That even worked fine and I was excited until I noticed that the servers were reporting the public IP assigned to the DMZ port as their IP when they sent mail. I then ran a test and that is the case. The servers - each with a public IP - are reporting the IP of the DMZ port. I can't have that because the mail servers need to announce a correct IP so the reverse lookup will match. Once again, a little gnat gets in the soup.

I have RV042G dual WAN VPN router as a gateway in my small office. My ISP requires from me to connect through PPTP VPN to have access to the network. I've configured my router with static IP and every time I connect a laptop or desktop pc I need to connect to the VPN with the Windows VPN client.

We have recently purchased a brand new RV042G VPN router, set it up, and had it running for a while without issues.
Now that we are actually trying to use the VPN functionality, the router becomes unstable after a while, showing "out of memory" lines in the logs, and after a day or two the VPN stops working completely and the web interface becomes completely inaccessible.
This issue happens when using any sort of VPN that's supported by the router.
