Security / Firewalls :: Wireless Router Cannot Pass From Firewall To Get IP From DHCP Server
Sep 22, 2011
Recently i had suffering with wireless connection problem, currently my wireless router connected to WAN directly, after that go into firewall and then go thru switch to end user PC, for LAN user there is no issue, but for wireless connected PC it is prompted with limited connectivity problem(DHCP is disable on router), after check with ipconfig /all. it seem likely due to wireless PC cannot get the IP from DHCP server. i am using DLink615 router. i had checked firewall setting there is firewall policy that connected all router ip into company LAN, but i don't think there is DHCP VPN setting up. is there anyway i can go thru firewall and get IP from DHCP server because if i set up DHCP on router, it cannot pass thru and access to LAN.

At my small business (30 employees) we currently don't have a hardware firewall. Should I have one? If so what do you recommend? We are all connected to a Windows Server 2003 domain in one office building.

My computer's virus protection expired so I Googled a free one and downloaded it without doing much research on it. It contained a virus and now it's disrupting my computer. I ran Microsoft essentials security and found malware and it removed all threats. The virus is disrupting my connection to the Google server. I cannot use google web, images, or mail but I can maps. I tried following the steps suggested here but my host file name is different and contains different information.[CODE]

I can't seem to figure out which one I should go for. I'm thinking Kaspersky would have greater security but I'm not familiar with AVG's server level security.I don't need all the bells and whistles such as file encryption or password storage. I'm simply after a really strong AV for the server. Another one is VIPRE although I've heard it can take a while to configure it unlike Kaspersky which is pretty straight forward.

I set up my daughter's Dell laptop last year to our WRT54G wireless router and I'm trying to connect to our wireless network now with another laptop (a new Dell) and can't find (or remember) my security code or pass phrase. Is there any place on the old laptop that I can access this info? How can I configure the new laptop without this info?

I was under the impression that those global addresses that we used with NAT were from the outside IP addresses range?Lets say my outside IP address is idk 192.112.40.11 /30 and I only had two usable IPs (since you can't use network and broadcast IPs) so how would I set up NAT for a couple of Inside addresses with a shorting of addresses like this? Idk if that makes sense what I'm trying to say

I've been trying to open ports 5800 and 5900 for UltraVNC and checking them with online port checkers, but they are always listed as closed. I've even tried taking town windows firewall, my router firewall (although as soon as I disable and apply, it automatically switches back to enabled again), and also DMZ'ing my router. I wonder if it might have something to do with my new modem, but in the config page for that, the advanced settings are locked out. the modem is an arris TM722G, and the router is a linksys wrt-54G with DDWRT firmware.
I'm running windows 7 x64 and using a static local IP, I want to be able to use DynDNS to connect to UltraVNC.

I installed Comodo Firewall today, and I couldn't access my Internet from then. I actually liked it's UI and all and want to keep it. The only something that I felt that might be causing the problem is "Use Comodo Secure DNS Server"? Is it likely the reason to be the cause of the problem?

We have a Cisco ASA 5520
We are attempting to setup RRAS on Windows 2008R2 using L2TP. Server is on the inside of the network at 10.10.10.20 our ASA is 10.10.10.1 its outside interface is 68.0.0.0.3/28.
I set a static NAT rule to allow all traffic pointed at 68.0.0.4 to be directed to 10.10.10.20 and have ACLs allowing the following.
esp, ah, udp/500, udp/4500, udp/1701
Mac Clients have no issues with but windows clients seem to hang and never connect. I know the ASA configuration is somehow to blame, if I attempt to connect to LAN IP (10.10.10.20) from withn the same network every thing works fine (making sure all the Windows Issues are covered).We have 2 other IPSEC tunnels established to teh ASA from our COLO and a Satalite office, not sure if this makes it any harder.

I cannot connect via VPN PPTP (normal setup in windows xp), I have managed to connect over VPN direct connected to internet, through the router (WRVS4400n) if I turn off the firewall. But I cannot connect with the firewall enabled,One more thing, the device is on and I have enabled the passthrough (and 'Multicast Passthrough' in firewall basic settings) for all available options where one of the options is PPTP.

I'm having some trouble with my P660RU-T1 configuration. I have recently set up a linux SFTP server at my home and am trying to access it via my public ip (eg 1.1.1.1), the problem is this public IP goes to the router which doesnt pass on the requests to the server.Last summer when i first messed around with this i had no problems with using the public ip to access the server, its only recently.

I'm new to IT, and have been put in charge of managing our servers hile my boss is on vacation.We currently have a Sonicwall Network Security Appliance that handles our Firewall/VPN and have web content filtering set in place.I have a user who belongs to 2 CFS policy groups that we have set up. I've double checked with Active Directory, and he is a member of both groups.
This person SHOULD have access to Job searches/ and Restaurants,but receives a "content blocked" message on his browser.It appears to me that the settings in Sonicwall are correct, as well with AD member groups.
