Linksys Wired Router :: Does RV042 Firewall Support Port Forwarding
Aug 5, 2011
I am using an RV042 router/firewall -- firmware v1.3.13.02-tm -- connected to a cable modem.I have one public address (WAN1) assigned by my ISP's DHCP server.All my machines on the LAN have static IPs. (RV042 DHCP Server is disabled.)I have set up port (80) forwarding to 192.168.1.101. The HTTP port forwarding does work if an http client on the LAN sends a request to url...But I cannot get a response if I send a request to url... from a machine on the WAN.I did configure Access Rules to allow http traffic (and then tried to allow *all* traffic) between a single IP on the WAN and 192.168.1.101.
The incoming log table shows a connection is made from the http client on the WAN to the correct http server on the LAN, but there is no resonse from the LAN to the WAN.Is my configuration the problem, or is this feature not supported by the RV042 router?Could my cable modem be blocking outbound traffic?

I have a system with a RV042 managing the internet connection.Behind the RV042 I have an e-mail server and a development machine that I access through SSH.My problem is that if I forward port 25 to my internal e-mail server it bypasses the firewall rules.I have an external vires and spam scan host that is the only one I should accept incoming email from - but it seems that whenever you add a portforward then it bypasses the firewall rules.

I want to upgrade my router but I need a router that supports more port forwarding entries for my applications. I have my eye on the WRT310N router but I need to know how big its port forwarding table is.

Continued from [URL] which appears to have been closed by a moderator with a reference to Cisco small business website, but the registration there doesn't work, all buttons are inactive etc.
I just need to know what to do with this RV042. I have two modems, a cable and an ADSL. Both are configure correctly, in bridge mode. Both work fine when connected to WAN1, but when connected to WAN2 they never go online (dont' get IP address). The connect lights are on but they never go online.
Firmware Version: 1.3.13.02-tm

I have a new (about 4 months old) RV042 V3 4.0.0.07 firmware that I am trying to use in fail over mode. I have a SOHO and I normally use cable Internet connection. It is quite fast (15 megabit), but not super reliable. I have added DSL (3.3 megabit) which is five nines (supposedly) but not so quick.
I have a Westell 7500 wireless DSL modem located in the basement, where the telephone lines enter the building. This gives me a wireless link to the second floor server room through a wireless router that connects to WAN 2 of the RV042. The cable modem is in the server room and connects directly to the WAN 1 of the RV042. The cable works, but when it goes down, the DSL link comes up but does not allow Internet traffic. The RV042 is set up as a Bridge and I have set up port forwarding to get the cable to work and used similar firewall commands to route the traffic if the router switched over. I suspect that the problem is in the port forwarding (port 80) or the firewall rules(which are pretty simple) because everything looks like it switches over, but it just doesn't work on WAN2.

I have a BEFSR41 ver 4.3 and I upgraded my firmware to 2.00.4.8 from within the router. Had a problem with the flashing power light. Resolved the issue after reading another post on this forum using the TFTP utility. Now, however, if I go into either Port Forwarding or Port Triggering and change anything, there is no Save Changes button to click on in either page. They are missing. If I click away, or close the browser and come back, all changes I made are lost. I have tried reloading the firmware at least four times. I've powered off, pressed the reset button and any combination of these that you can reasonably think of. The buttons are gone! I have tried accessing the router from both IE and Firefox, accessing the router from all the machines on my network, to no avail. Everything was working fine before the upgrade, of course. The router does not have the option to save the old firmware before any upgrades are made. The original firmware has been overwritten so I can't go back to it.

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 have a RV042 router on a single WAN and an internal LAN. I have configured port forwarding as follows: HTTP[TCP/80~80]->10.0.0.6HTTPS[TCP/443~443]->10.0.0.6IMAP[TCP/143~143]->10.0.0.5IMAP SSL[TCP/993~993]->10.0.0.5SMTP SSL[TCP/587~587]->10.0.0.5
Everything works just fine when I have the firewall DISABLED. However, when I enable it the behaviour is erratic. 1 out of 10 attempts to connect to ANY port forwarded works. Almost all attempts time out. Notice that this happens even if using only the default firewall rules (which should be bypassed by the port forwarding as I read in other posts).
My second try was to create firewall rules manually, overriding the default ones. I tried adding rules from source WAN1 (where my connection is) to ANY and to SINGLE IP's on every port. Nothing seems to work.
I don't know what I'm doing wrong, this is really bugging me. I had to turn the firewall off so we can access our servers from outside the office. This shouldn't have to be done.
Just found out that my firewall is getting LOTS and LOTS of Blocked - SYN Flood entries. I think this is why we are having trouble with the firewall. Could this be the problem? I have no idea where all these SYN packets are coming from since they appear with spoofed IPs or come from different bots all over.

I have a Cisco RV042 Wired Router. I've got a static IP and a MS Small Business Server in my Router Network. I have forwarded the essential ports to use the IIS and the Exchange Server of my SBS2011 (https, http, smtp, rpc).
I can use the IIS, if the firewall is activated, but the exchange Server can not receive any emails. I have also created some firewall access rules for the mentioned services but without success.

When the WAP54G is set up as a repeater for a WRT54G, will a computer connected to the LAN port on the WAP54G be able to connect to the network? I know it will see the WAP54G if I manually set it's ip address.
I guess I want it to act as a wireless NIC for the desktop while also operating as a repeater. Is this possible? If not, will one of the other AP settings like Bridge allow the wired connection to connect to the other side of the network and give wireless access to wireless devices? I've hacked up and attached one of Linksys's diagrams to show what I'm trying to do. It seems to me the easiest thing to do would be to buy a wireless NIC for the desktop.

Currently I have the RV042 router working in a dual WAN set up, it is configured to accept connections on numbers of ports like 80,443, 25 and forward them to a local ip.
The problem is this only works with WAN1. Is it even possible to forward ports for connections coming in over WAN2?

I have a RV042 with Port Forwarding configured for RDP. This Port Forwarding Rule is being applied before my ACL - so subnets that are not authorized through are being allowed in. Firmware version 4.0.0.07.

I have tried replacing a loaner RV082 V2 with an RV042 V3 router with firmware 4.0.4.02. All worked well, including the site to site VPN. However, in spite of the fact that I have ports 443 and 4125 forwarded to the server (192.168.2.10), we are unable to connect via RWW. There is no such problem with the RV082. What is different with the way we configure these V3 routers for port forwarding?

I'd like to setup a WCCP in those routers, but as I read, it's not possible.
Another way to circumvent this limitation is to foward a request to the router from the LAN port 80 to a LAN IP, something like:
LAN 1 192.168.1.100:80 -> router -> LAN 2 192.168.1.101:80

I would like to the the RV042 for a one to one NAT, but I need it to NAT to an address that is not on it's local subnet. I have it routing properly to the address, but web interface only allows adding an IP on the local subnet. Is there a way around that?

We have 3 Cisco RV042. These were purchased to permit VPN from two branch offices to our head office. VPN is required to permit the two branch offices to use Avaya IP phones to connect to our main head office switchboard.We also have users on Blackberry and Apple iPhones to collect their mail through OWA from our Exchange 2010 server.
I've noticed in one of your threads that the RV042 routers configured for VPN do not permit the use of HTTPS to connect to OWA and that seems to be the problem for us. Since installing the VPN our OWA access is not possible.
What can I do to resolve this problem and what router would you suggest that I could use at the head office to enable the two branches to connect VPN to head office? And if there is a suitable router, would I need to replace all three?

I'm experiencing quite a slow vpn performance. I've tested different scenarios.* Windows XP with built-ín pptp client and Shrew ipsec client* Linux built-in pptp* wireless and wired connections? I never managed to go above 1MBps neither with windows or linux. I managed to go up to 3MBps using the Shrew client.I've also checked mtu settings and everything seems to be fine.

I am converting from a Cisco Model 850 to a RV042, all is well so far but I cannot implement one feature I had on the old router.I want to do one to one nat from one internal ip to one external ip but I only want to use one tcp/ip port.The command to do this on the old cisco 850 was this:"ip nat inside source static tcp 192.168.1.181 80 75.xxx.xxx.181 80 extendable"Can this be done with the RV042?I can do one to one nat but it include all ports.

LAN L1, with IP addresses 192.168.10.x, for Company C1
LAN L2, with IP addresses 192.168.11.x, for Company C2
I have networks separated: different racks (but very closer fisically: a wire can be thrown), different gateways (to DSL), but both LAN's must connect with each other. I have acquired two RV042, one for each company to create VPN's (permitting telejob).

I tried to upgrade the firmware of my RV042 router. I downloaded the file (RV0XX-v4.0.0.07-tm-20100819-code.bin) and check the cheksum. When I try to upload it, I have the message "413 Request Entity Too Large". How can I do ? Should I unzip the .bin file (it's about 30Mo) ?

We have a Network set up with a RV042 router. Router is hooked up to Cox Cable and ATT DSL. Currently have 20 computers hooked up to the router all using Static IP addresses. Setup has been in place for over 7 years. I want to set up a Wireless Access point on this network. The problem is, I can't seem to get DHCP to work right even WITHOUT the Wireless Access Point. I have taken one of the computers that works great with a static IP and changed it to be DHCP, I have enabled DHCP on the router and set the from and thru parameters for the IP assignment. The computer will connect and get an IP address and it allows me to see all the INTERNAL servers on the network but going to the Internet is REAL FLAKY. I usually have to refresh 5 or 6 times to get a web page and sometimes even that don't work. If I do get a page to come up there is about a 10% chance that it will bring up a subpage of that page without doing a refresh 5 or 6 times. Its like it won't hold the connection to the Internet. I did notice one thing different in the User Manual of the RV042 that is different than all the other Linksys routers I have worked with. It says that when you enable the DHCP on the router, you then make sure ALL computers hooked to it are set for DHCP. All other routers I have worked with do NOT use that word ALL. Am I missing some setting or is this a binding thing where you are either ALL static or ALL DHCP?

Small office, 2 RV042, 2 DSL connections. 1 is used striclty for the business side, and the other is for our CCTV network. They also have seperate DSL connections as we have 2 external IP address for clients to connect remotely. We don't want to take away our exisring setup, but would like to bridge both networks so a few of our internal clients can connect to our CCTV network and use some of the devices. Right now they come in on VPN but its not as fast.Is this doable without adding additional hardware? Both networks need DHCP enable as well.

I have been running a email/web/ftp server on one server for 9 years. I have currently acquired a Barracuda spam 300. I cant get the emails to go thru the barracuda first. Here is how it is setup: my email and web come in thru one outside address..call it 166.5.5.5 I have a 1 to 1 nat for 166.5.5.5 to 10.0.0.2 (email/web/ftp server) ports 25 and 53 are forwarded to the 10.0.0.4 (barracuda) then out on 25 to my 10.0.0.2 no emails go thru as long as it is set this way I can nat the 166.5.5.5 to the barracuda first and emails go thru, but I lose my web and ftp will this router work for me? I was told that i needed to change mx records for email to 166.5.5.6 and then forward nat on that address to the barracuda. I dont really want to change mx records for 10-12 email domains.

I am currently using Netgear FVS338 Routers / VPN Devices in 3 different locations and honestly I am not happy / impressed with them whatsoever.I have been doing some research and came across the Linksys RV042 and RV082 devices that caught my eye. The question is what is the VPN throughput of these devices?I have gone over the website, spec sheets and they only really say the throughput of the LAN Links and not the WAN Links. I currently have very reliable 20Mb+ Synchronous connections between all 3 sites and have not been able to get any good performance out of the Netgear devices and contacting their support is a joke. They can't tell you anything other than it should work or we will swap out the unit. Well if I have 3 of them that have been purchased at all different times I don't believe that they are all having the same issues. What these units 3DES VPN Throughput and will more than likely be purchasing 3 of which ever once suits our needs immediately.

I have a RV042 router and we are trying to set-up our OWA for outside access. I can't figure out which ports or which page those ports are on to open them. We are a small company and we do not have IT except for ourselves. The internal network works fine but i can't get the Exchange access from outside.
