I have a fibre connection on the dedicated WAN which was working perfect until someone somewhere cut through the line. The SA520 fell over to the Optional WAN port which is basic ADSL line which is connected. Logmein client is online too.
But it refuses to browse webpages, appears to be a dns issue or firewall or both.
I have added the ISP dns addresses into the forwarders on my server.
I have an SA520 that is being used as a front end firewall. Behind it I have an IP PBX. The VOIP provides are registered and I can make outgoing calls. However It appears that the SA520 is either blocking or not routing the calls. I have opened the ports recommended by both the IP PBX and the VOIP provider. What do I need to do to make incoming calls through the SA520?
View 1 Replies View RelatedWe are using a SA520W as our primary router and have a fiber connection attached to the default WAN interface. We would like to improve our uptime using a secondary internet connection on the optional WAN interface.
We have bought a dovado tiny 4g router for this other connection. It acts as a dhcp server but the Cisco router does not get an IP from the dovado router. The router works as expected when connected to a normal computer. But somehow the cisco router doesnt get an IP.
I have also tried to set a static IP for the Cisco router but that didn't work either. The dovado router is setup do deliver ip in the range 192.168.0.2-254
I am currently trying to configure a Remote Access VPN on a SA520 (Primary Firmware Version 2.1.51) using Cisco VPN Client (Ver 5.0.07.0410)
Until now i have connectivity from the SA to the LAN and i can connect using the Cisco VPN Client to the AS:
[IKE] INFO: IPsec-SA established[UDP encap 12856->4500]
[IKE] INFO: IPsec-SA established[UDP encap 12856->4500]
It gives me an IP from the pool but i can not reach through ping to my LAN.
I am trying to configure the DMZ on my SA520 router but without success.After a lot of tests I reduced everything to a very simple test case that is not working: I setted the "Optional Port Mode" to "DMZ" and enabled "DHCP Server" in the "DMZ Configuration", but DHCP on the DMZ does not assign any address.I am wondering if my optional port is broken or not.

We have been able to configure the VPN server on the SA520 however the connection is very unstable.We use OS X 10.7 lion built-in Cisco compatible VPN clients and this is a typical output of ping from 3G mobile network to a server inside the office network. It works the same way also if I am trying to access from my home ADSL connection so the problem is not the instability of the 3G connection.

View 2 Replies View RelatedIs PVID the same thing as "native vlan"? Can the native VLAN be changed on a SA520? Currently I believe it to be 1, I'd like to change the native VLAN to 10.
I have a scenario where I have a prexisting production LAN of 192.168.1.0/24 . It's a small organization (a church), but they purchased 3 Aironet 1130ag units. They want to have a "private" WLAN that is part of 192.168.1.0/24 , and a guest WLAN of a different subnet (I chose 192.168.20.0/24) . The two should never meet. There will likely never be a guest computer connected via ethernet. Guest computers would always have to connect wirelessly.
I left VLAN 1 on the SA520 192.168.75.0/24 subnet as default.I created a VLAN 10 , 192.168.1.0/24 subnet, and I created a VLAN 20, 192.168.20.0/24 subnet.Ports 1-3 of the SA520 are members of VLAN 1, 10, and 20 (cannot remove membership of VLAN1, which is pretty annoying).
Both are secured by WPA, and when I connect, the proper DHCP subnet passes from the firewall through to the wireless client, for each respective SSID.Ultimately, I'd like the SBS 2003 server to handle DHCP for VLAN 10, and have the SA520 handle DHCP for VLAN 20, but i'll take what I can get.
The original production LAN is connected via an unmanged switch.I'd like to trunk the unmanaged switch to Port 4 on the SA520. However, since the PVID (native vlan?) of SA520 is 1, and I cannot make Port 4 on the SA520 ony a member of VLAN 10, then anything traffic coming from the unanaged switch will automatically be tagged with VLAN1, correct? Thus causing the already existing production network to start receiving DHCP from the firewall in the 192.168.75.0/24 range.
How could i make a vpn tunnel between a router SA520 and a central UC540.
View 3 Replies View RelatedIs there a way on the security appliance SA520 to remove someone from the DHCP lease client manually rather than setting the DHCP lease time to expire in less time like 4 hours or 2 hours. I was able to do this on other routers by highlighting the connected device and click remove. If not any recommendations on how to handle the device that are attached via DHCP and the person is no longer here, but the lease time is not up. I have set DHCP lease time to 4 hours.

View 2 Replies View RelatedI have 2 ssid signals setup at my workplace.
the 2nd one is for all guests and it's isolated from the lan+trusted(1st one) with a vlan feature.
the 1st one is for all trusted devices over wifi. the wifi channel is setup to allow mac addresses of the two asante security cameras. the cameras upload videos to an ftp on my server. the two will connect to the router at first, I can ping them or see them in 'my network'. give it a little time and they disappear. then I have to power off/on the router or the cameras to make them work for a few minutes. the process repeats.
the cameras make lots of connections to the ftp server. I'm suspecting they're flooding the router and it blocks them. occasionaly they will come back for a minute or two and disappear again as if blocked/unblocked.
I added their mac addresses in hopes of making them 'trusted' devices. I've tried them on both ssids. I checked and unchecked firewall/security checks and icsa settings. all other devices I tried, multiple phones and laptops work without problems on both ssids and they don't get blocked.
I have an RV082 (running 2.0.0.19-tm) set up as the gateway to the Internet on my home LAN, and connect to it through several switches / hubs around my house. Randomly, and from various connections around the house (which are all plugged in to different ports of the RV082), a Web request will fail to load, giving a "Server not found" error in the browser. When I look at the log in the RV082, it says, "Connection Refused: Policy Violation".
It seems to be just blocking the DNS requests - everything else appears to go through normally. For example, I get the message "Looking up domain name.com" in the bottom corner of the browser and the request fails, displaying the Mozilla "Server not found" error page. When I click the "Try Again" button the page, it goes through just fine and everything works.
I don't have any services running behind the firewall, and do not use the VPN settings. Here are my current firewall settings:

View 3 Replies View RelatedI need to access a shared folder over a VPN connection. Very simple host network: no Microsoft server, no AD. Just a WRVS4400N router and a peer-to-peer network.
Purchased a second WRVS4400N router to create VPN from SOHO and configured via VPN Setup Wizard.
When at the office, I can map a drive letter to a share on the other computer, as follows
net use f: \192.168.1.111MyShare /User:MYSELF mypass
However, when try same command over VPN, I receive the response:
System error 53 has occurred. The network path was not found.
I also cannot net view the other computer -- same error. However, I can successfully ping 192.168.1.111.
More info:
Routers have latest firmware.
Over VPN I cannot browse network via Windows Explorer (Win7 Network Neighborhood shows only my own PC. In the office I can see the other computer and the NAS appliance "NAS01").
I also cannot connect by entering \192.168.1.111MyShare into Windows Explorer's address bar (although I can do that successfully when at the office), or by choosing Map Network Drive from "Computer".
However, over VPN, I can get into NAS administration via https://192.168.1.3 and I can print to the office TCPIP printer (192.168.1.222)

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.
