Cisco Routers :: RV082 NAT Table Too Small
Mar 15, 2013
I have an RV082 10/100 8-Port VPN Router and have configured the NAT table to allow for remote users, however I've run into an issue. It seems like there is a limited number of entries that you can put in the table,10, and I need to configure about 5 more IPs. Any way to expand the NAT table, or alternatively recommend a different router. I would also be willing to add another router to the network, but I have little experience doing that.

I saw older discussions over WOL and RV082/RV042. As router blocks broadcast packets from internet to lan, to make WOL work, i should change router's ARP table using telnet, probably with V1 and V2 versions this action was possible, but trying telnet connection (http://<Router IP Address>/ sysinfo123.htm?ConsoleSimulation=1 with RV082 V3 nothing appears, and telnet connection on standard port (23) fails.
How to make pass WOL magic packets through a RV082 V3 from internet to LAN ? Using simply port forwarding don't work, as router discard broadcast packets incoming from internet.

I'm looking for a Cisco device to run a full BGP table with a 60Mb link. And one of the main restrictions is that my traffic is almost 100% real-time (voip). So the average packet size is small. Today we own a Cisco 7204 NPE400 with 512Mb RAM. I think even though I upgrade it to a G2, due to the small average packet size, the router will be near to its limit. Maybe a Cisco 7300 NSE-150? Or should I think about a switch?

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?

In datasheet of WS-SUP720-3B - link- was said that are only supported around 256K routes (fib?rib?).With this value I can't get 2 full bgp - that is around 850K ..
The supervisor is that control this or just memory ? I said this because I have a 7204-npe-g1 whith 2 fullrouting and 1G of and he are ok..

We're getting the following message in the logs when we ry to connect: encrypted Informational Exchange message is invalid because it is for incomplete ISAKMP SA
One of the router is a V2 and the other is a V4 if that makes any difference.

I am currently using 2 routers. One is a 2wire router with stock firmware it is connecting to the internet and can't be altered all too much, it also has a PC connected to it. The other is a WRT54GL with Tomato on it with pretty much EVERY other PC and device connected to it, it is also connected to the 2wire and DMZ'd through it.What I want to do is somehow allow everything on the Tomato router to have access to the 2wire router's PC. (For media access or printers or whatever on Windows 7)

I'm trying to configure the newly install Cisco Small Business router SRP527W. This router is provide by one of Malaysia ISP
Problem I found is that, when a user (me) login to the router via web access, than I request my colleague (B), to test the feature I set to the router and try to login to the router via web access at his laptop.
Suprise, suprise, user B redirect to the basic setup page with Admin privilege without enter username and password. By upgrade latest firmware still unable to solve it.

The router keeps loosing connection to the internet. I can still log into the router locally but cant connect out or in from the internet. Which is a big problem as i use this device remotely. I have tried different firmware (.9, .19, .27) the .19 seems to be the most stable but i am still having problems. The only way to rectify it is to reboot the router. Is there a fix for this or a way to schedule a reboot on the router.

One of our locations recently upgraded their VPN router from a Netgear FVS318 to the Cisco Small Business Router RV042
My location uses the Linksys RV042v1.2. We can't get the VPN to connect. The VPN set up screens are similar, but there some parameters that we had to adjust. The SA Lifetime parameter for the Cisco Router defaulted to 86400 Secs (Phase 1 & 2) The SA Lifetime parameter for the Linksys only goes to 28800. So we adjusted the Cisco RV042 to match out Linksys RV042.
That's the only difference in the screens that I see. The Cisco has additional paramters under "Advanced", but they're all unchecked by default.
When they shipped the Netgear FVS318 over to us, we get the VPN to function, however, the Netgear has a max throughput of 10Mbps. (we get 4-5Mbps on Speedtest.net). The RV042 gives me over 40Mbps (Optimum Business w/Ultimate)
I tried both firmware updates on the RV042v1.2
RV042 v1.3.12.19
RV042 v1.3.13.02
Any compatibility issues between the different versions of the RV042?

I am having difficulty with gateway to gateway vpn on RV042.I have site A and site B, both have static IP address,local IP at site A is 192.168.1.0 local IP at site B is 192.168.5.0I have configured each site as directed in the documentation, the sites connect ok within the admin consoles, I cannot browse any resources from either site. Site A is a domain.local and I am part of that domain at site B. I can ping site B local address from site A and vice versa however I can not ping any of the servers or NAS devices on either network. the only device I can ping successfully inside the network is a phone server (splicecom unit).
I have read various posts in the discussion boards but have found no resolve. Internet access is fine from either site. I think that it could possibly be a DNS issue but am unsure, should I add DNS entries in the advanced section, if so what DNS would I enter?

I have been trying to configure a local DMZ on our network with the Cisco Small Business RV220W router, running the latest 1.0.3.5 firmware but it doesn't seem to be fully functional? Does the DMZ feature actually do anything at the current state of this router? Because when I tried to DMZ host a computer on our local network I still had to manually port forward different applications in order for people to reach it from WAN.
For instance when trying to host a game session, utilizing TCP port 7777 it didn't matter whether I had enabled DMZ or not, I was still required to manually port forward the port to the DMZ IP-address.
Doesn't this defeat and eliminate the whole purpose of the DMZ feature in the first place?

I currrently have the RVS4000 and am looking at the RV180, but I'm having an issue with the RV180 supporting the Dynamic DNS service I need (see here). In that discussion, it seems what would be ideal for me is a router running IOS so I could customize the Dyanmic DNS client on there to fit my needs. However, is there any "affordable" router running IOS that's similar to the RV180 tailored to a small business without getting an overkill router?
Here's my basic needs:Router either compatible with DNS Made Easy's Dynamic DNS service OR has the ability to customize the Dynamic DNS client on there so I can adapt it for DNS Made Easy.I DO NOT need wireless. We only need Ethernet/wired.I prefer Gigabit Ethernet.We're not currently using ProtectLink, so if it offers the ability for it, great, if not, fine.We have our own VPN service and don't need to access the network remotely (just remote into one device using Dynamic DNS), so if it has built-in VPN, great, if not, fine.I'd like IPS included. Our RVS4000 has it and I like this feature.We're switching to cable broadband and VOIP through our cable company, so QoS should probably be included.

Cisco RV016 Small Business Router (firmware version 4.0.4.02-tm) . We have several old RV series Linksys, and the interface seem identical to this new Cisco version so it isnt difficult to have it configured. However, I am facing issues. I cannot ping from untrust to WAN IP of the router. However pinging from trust to any IP is just fine.
I tried disabling firewall, I also created a firewall rule that allows all ICMP from ANY to ANY. I also tried All traffic from Any to Any. But still the WAN1 and WAN2 IP addresses (Multiple ISP) still does not reply to ICMP.

I was wondering if anyone has seen their VPN User Connection Status Table empty even though you know for sure clients are connected? I connect with my iPhone to the PPTP VPN successfully and it works fine but there's no entry for the connection on the VPN User Connection Status Table. Is that normal? Does the router only collect data about Windows clients?

I have recently purchases a Cisco srp547w for my organisation. It is working fine with one SSID enabled. I have configured everything with no problems using the Web interface. However, whenever I click the Edit button, in the Security column, in the Wireless Table under Basic Wireless Settings I get a pop up message which says :"Some values have been changed. The router must restart the wireless module to take effect.Please wait several seconds" I have tried this using 3 different browsers and get the same behaviour in each browser.

I have a problem connecting SRP541W to my ISP (L2TP). Connection is established, but default routing table is wrong: instead of gateway I see Server IP: [code]
In similar situations other users of my ISP with Cisco routers (IOS) solved this problem by adding command no peer neighbor-route but i can't do it through the WEBgui...

We have an RV082 setup with WAN to the internet and LAN IP of 192.168.188.1.If I add a static route like so:
network: 192.168.166.0
mask: 255.255.255.0
gateway: 192.168.188.2
hop count: 1
interface: LAN
The device with IP 192.168.188.2 will be connected directly to one of the LAN ports on the router.Will that work to route, trying to get to 192.168.166.0 to the IP of 192.168.188.2?It just seems odd because the packets would hit the router then go back out through the LAN port.

I have a Meraki Firewall that sits behind my Cisco RV082. The Meraki is setup to run a VPN connection with my server but I am having problems passing the VPN traffic through properly.
I have 2 Uverse Internet Connections that the RV082 using load balancing so that they are shared. I have 10 static IP's.
I am trying to come in on one of my static IP addresses throught the Cisco RV082 to the Meraki and after doing a capture on the meraki it appears that it is starting to receive data to intiate the VPN connection but when it sends data back to the VPN client machine it never makes it.

I have reset my RV082 router (both wit the reset switch and the factory default wizard) and run the setup wizard but regardless I can't connect to shaw.ca which is my service provider. I notice that if I use http://192.168.1.1 the browsers (IE & FF) default to https://192.168.1.1 and then I am prompted for a certificate. I can enter if I ignore the request but after getting in I simply cannot connect to my ISP.

Is it possbile to NAT to other subnets with the RV082. It is on a 192.168.41.x and I have a phone system on a 192.168.20.x. After searching all over others are saying no.

I just set up a new Linksys/Cisco RV082 router with the intent to get VPN working from outside the building. I have gone through the setup and while everything looks good, I have not been able to connect yet. I have tried everything that I know how, and am now hoping to get the answer from some pros.
Here's my setup. We use Comcast Business class internet. The modem is plugged into WAN port 1 on the RV082. I'm using the router as a DHCP server, that is working fine. My local subnet is 192.168.0.0/220
Right now all I want is to be able to log in as a client using QuickVPN. I set up one user and a client to VPN tunnel using the router's config page. Here's the settings I have:
Tunnel Interface is setup on WAN1, checkbox is enabled.
Local Group Setup
Local Security Gatewaytpe: IP Only
Local Security Group Type: Subnet
[Code]....
It seems like something is blocking the connection, but seeing that I have tried this after disabling the firewall completely it doesn't make sense to me. I also went into the config page for the modem and set up the router as a DMZ. I have also tried connecting with the client built into Windows 7, but that doesn't work either, I just get "connection failed with error 619"
I have the port in QuickVPN set to auto, but have tried both 443 and 60443 with same results.
I ran a port scan at [URL] and it shows I have 3 ports open...80,443, and 1723

I have a VPN tunnel from one RV082 to another, first router has IP range of 192.168.1.0 and the second one has range of 18.18.18.0, the connection works fine, here is where the issue starts, I am at a PC in the 18.18.18.0 network and I ping an IP in the other one e.g. 192.168.1.50 and it pings fine, but when I try to RDP into it or do anything to it I get no response, is it a firewall issue? Is it a NAT issue? I am at a loss, now that IP i mentioned does have RDP enabled and working because it is being port fowarded in the 192.168.1.0 router and I can access it through the public IP.
Also a workstation with a static IP 192.168.1.18 I can ping it if im in the local network but if I am in the remote one I cannot at all.

we have an RV082 router that a few days ago started restarting itself after normal usage.The simpton is that when people come to office, starting using the Internet the RV082 resets. It stays online for 3 to 12 minutes and then it resets again.
clicking on Reset to Factory Default in the web interfaceafter the reset, I confirmed that it was reset to factory default I reset it again using the reset buttomre-configure the RV082 manually.I also tested with another identical rv082 (hw version and firmware version) and after doing a backup of the config of the original rv082 and restoring it in the new rv082, the same problem happends.

I've been playing around with the Cisco RV180s for a while now and have come across a problem with the subnet calculation in the static routes and routing table. Essentially, if I configure up a static route for a /16 it's entered in the routing table as a /13. If I add a /24 it's entered in the routing table as a /16. I haven't tested every subnet size and combinations but this looks like a fairly fundamental maths bug.
As a side note, I notice that the 1.0.1.9 release notes state the removal of SSH Server, however, I can not find any reference to it's existance prior to 1.0.1.9, did/does it exist in 1.0.0.30 and if so where? .
Screenshots are below and an extract from the configuration file for reference.
From the config file:
route = {}
route[1] = {}
route[1]["active"] = "1"
route[1]["dstIpAddr"] = "8.8.0.0"
route[1]["gwIpAddr"] = "192.168.1.250(code)

Just purchased a RV082 and once I switched a bunch of users over to it I can no longer access the web admin section. I have tried using both IE and Firefox and have used multiple workstations. I get to the login screen but it doesn't get any further. I am running the latest firmware v4.0.4.2-tm. It works for a while then just stops. The only fix is to turn off the device and back on and then it starts working again.
I've seen this issue on other small business cisco devices and had to stop using this because of this issue and switch to a higher grade cisco product but was hoping that this particular issue would have been resolved now across cisco's products.

I just migrated our office network router to a RV082. While configuring it, I came across three problems:
(1) From our ISP we have four public IP addresses which I want to make use of for outbound traffic. With the previous router we used we could configure LAN IPs(ranges) to map to static public IPs. Does RV082 support this? I could not find an option for that at the web-interface. From what I understand the 1-1 NATing only goes both incoming and outgoign ways and actually is 1-1 and not the many-to-one I am looking for.
(2) How is it possible to configure incoming port forwards to use a specific WAN interface? Will it always be the primary WAN interface?
(3) Does the telnet access provide more configuration options? I could not log in to it with the same user credentials as with the web-interface.

we have a RV082 and have the DMZ option enable for a range of IPs within the same subnet of WAN IP and this works great. I have another range of Public IPs from our ISP that is not in the same subnet of the WAN IP and do not see a way on the RV082 to include this 2nd bank of Public IPs in the DMZ. Our ISP internet feed plugs into the RV082 WAN port and we have a switch pulgged into the DMZ port of the RV082 that is used to connect the public devices in the current DMZ. Both banks of Public IPs from our ISP come over via the ISP internet feed plugged into the WAN Port. My question is, if I cannot configure a DMZ rule to allow this 2nd range of Public IPs to "travel" to the RV082 DMZ port.
