how statefull firewall works for udp?
by Tarig Ahmed 21 Jan '11

21 Jan '11

Dear All Hi Default configuration for statefull firewall is to allow traffic form TRUST ZONE to UNTRUST ZONE. As I Know those device will use some feilds in the TCP Header. But, how the firewall will handle this policy for none TCP traffics (udp, icmp, and IPsec)? I think understanding this will help me in the designing. Thanks -- Tarig Yassin A. Ahmed www.suin.edu.sd skype:tarig_sudan1

Software DNS hghi availability and load balancer solution
by Sergey Voropaev 21 Jan '11

21 Jan '11

Does any one know software sollutions (free is preferable) like as cisco GSS and F5 BIG-IP? The main point is that DNS-server (or dns server plugin) must be able to monitor server availability (for example by TCP connect) and from DNS-reply depends on it. I know that it is possible by BIND with set of script. But we are trying to find more usable solution with frendly interface. Thanks a lot.

Looking for an Akamai contact, strange DoS traffic sourcing from Akamai sources
by Tom Beecher 21 Jan '11

21 Jan '11

I'm looking for an Akamai contact to try and address a strange situation. We have multiple sites across the country that aggregate 56k dialup customers. Different sites are randomly experiencing inbound traffic spikes that are overwhelming the uplinks to our carriers, causing DoS situations. These spikes far exceed the bandwidth that could possibly be used by the number of dialup customers connected. We've been able to trace the source of the traffic to Akamai boxes, but so far have been unable to reach anyone at Akamai to discuss the situation. We're attempting to get payload information, but the traffic volume is making it slow going setting up packet captures at these sites remotely. Thanks in advance, Tom -- Thomas Beecher II Senior Network Administrator LocalNet Corp. CoreComm Internet Services tbeecher at localnet.com

Re: Verizon FiOS Distribution Switch
by GP Wooden 21 Jan '11

21 Jan '11

Not that this is a requirement, but good practice none the less with this setup... Turn off cdp on the port facing the LEC... -graham ----- Reply message ----- From: "Chris Burwell" <cburwell(a)gmail.com> Date: Wed, Jan 19, 2011 2:56 pm Subject: Verizon FiOS Distribution Switch To: "NANOG" <nanog(a)nanog.org> I have a question about a Verizon FiOS business connection with an ethernet hand off and I am hoping that someone out there has done the same thing. We have a FiOS business connection coming into our building. This includes an Ethernet hand off into the usual Actiontec router as well as a block of 13 public IP addresses. The Actiontec router needs to remain in place with its current Public IP address. We have some devices from a vendor plugged into it for Internet access, as well as numerous cable boxes across the building that get their guide information through the coax interface on the router. What we want to do is take the ethernet hand off out of the WAN (RJ-45) interface on the Actiontec router and plug it into a hardened Cisco switch such as a 2950. Our goal here is to use the Cisco switch as a Internet distribution switch since we will have numerous test devices that will need to have a direct connection to the Internet. Our preference is also not to have all of the traffic from these other devices traverse the Actiontec router. I have a few concerns with this setup: Some articles I have read indicate that the hand off from the Verizon ONT may not be a direct Ethernet hand off so the interface it connects to may require a different config (Dialer or something). I am also concerned about any issues if the ONT or some down stream Verizon device may cause if it sees multiple MAC addresses coming across our link. We're not trying to cheat the system or anything, just to modify the Verizon setup to better suit our needs. Any advice or tips would be helpful. - Chris

Securing Border Routers
by Brandon Kim 20 Jan '11

20 Jan '11

Gents: What measures do you take to protect your border routers? Our routers are running BGP so I'm interested if there is any way to secure them without interfering with BGP? Is it normal to put a firewall in front of the border routers? I'm concerned about DDOS attacks mainly....although we haven't had any, I don't welcome them..... Brandon
