Used a pair of ASA 5520s in HA to firewall the internet edge and to firewall traffic between internal security zones such as web and application layers? If so, is this best done using different security levels or contexts?
I'm thinking of using a routed context for securing the internet edge and then using seperate contexts for the web and application networks. Contexts will route via a L3 switch.
We have ASA 5520 firewall.For broadband Internet access, we have T1 Router(edge router provided by ISP) which provides public IP's 198.24.210.224 / 29. We have usable public IP's 198.24.210.226 - 198.24.210.230 with default gateway 198.24.210.225. We assigned 198.24.210.230 255.255.255.0 to the outside interface.
If we connect the ASA 5520 outside interface directly to T1 router, can all packets with destination addresses 198.24.210.224/29 reach the outside interface without using other device like another router or switches?I just assume that only packets with destination address 198.24.210.230(outside interface ip) can reach the outside interface from the edge router.Is it wrong assumption? If it is correct, then is there any way to route all packets with destination address 198.24.210.224/29 to the outside interface?
Apart from the ability to participate in BGP, is there any reason you should use a router on an internet edge rather than the SG-300 switch?
View 4 Replies View RelatedI recently ran into some problems concerning the use of a Cisco layer 3 switch (3560) as an Internet edge device to perform a simple static route between the customers network and the ISP POP router. Although this device can perform the routing at the edge for Internet traffic, I am concerned that this device has limitations when it comes to functions such as traffic shaping to the subscribed bandwidth of the Metro Ethernet access to the Internet. Since the 3560 could not conform to the 20 Mbps of subscribed bandwidth, any traffic beyond 20 Mbps was dropped causing performance issues with applications that use TCP. I am trying to find design documents or white papers that would either support or not support using a layer 3 switch as an Internet perimeter device instead of a router. I would like to know if Cisco has a specific perspective on this subject and whether or not they would ever recommend actually using a layer 3 switch model that is a 37XX or below?

-10GE interfaces
-can handle 1.5Gbps but scales up to 5-6Gbps different seasons
-take on full internet routes from 2-3 providers
-will live on the internet edge
What is the best way to monitor an Internet Edge router from the Internal network behind the Firewall?We want to pull more information from the edge router like netflow. We can use SNMPv3 and ACLs to keep the router secure.
But I am looking for the best config to keep both the router and firewall as secure as possible while still allowing us to monitor performance and faults.I am running an ASA and a 2821.
From My Router that connects to Cable modem i am unable to ping website 4.2.2.2I am able to ping all other websites fines.Same website i can ping from my pc and all other switches fine.Router has only 1 ACL thats for NAT.

I realize I'll need an SFP to get to duplex LC, but I'm not sure if I need a router, or if the ASA can function as a router for this application.

View 6 Replies View RelatedI have a 2504 WLC with a 1042 AP and I have it placed on my edge Cisco 3750 switch. I have the management interface of the WLC set on my WAN IP 71.x.x.x subnet range, and I have the WLC doing DHCP duties with a DHCP scope of 192.168.X.0. I have my DNS servers set on external DNS servers out on the Internet.I have two Cisco 3845 Routers on my edge network - one for each ISP with BGP protocol.
Since my native VLAN is 71.x.x.x, I added a sub interface on my main core router and gave it a 192.168.x.1 255.255.255.0 address for the gateway. Also, I added ip prefix-list iBGP seq 10 permit 192.168.x.0/24 le 32 to my main core router. On my secondary ISP router I added ip prefix-list iBGP seq 10 permit 192.168.X.0/24 le 32, and ip prefix-list OUT seq 10 permit 192.168.x.0/24 statements.
I added VLAN 10 to my edge switch and gave it IP 192.168.x.2 255.255.255.0, and the switchports that my core router and my WLC are connected to the edge switch, are in trunk mode with encapsulation dot1q 10. The switchport on my edge switch that the AP is connected to is in switchport access mode.
I can connect to the wifi with a 192.168.x.x IP address on my laptop, but I cannot get any Internet access. Is it possible to have the DHCP scope be in a different subnet than my WAN IP subnet, and allow guests to get to the external Internet only? Do I need to put the WLC somewhere internal on my network i.e. the DMZ and then tunnel the traffic out to the Internet with no Internal network access?
We have two 6509 will active/passive sup 720-3BXL cards in each and 1GB DRAM. Each handles full bgp routing table with 4-5 ISP(eBGP) connections. The problem we are facing is.. 6509 were meant for core/aggregation and seam to be wasted are edge devices. With each ISP added the DRAM creeps up to a point were is it 80% utilized.
I am looking to replace both 6509's with routers which were meant to work on the edge. As mentioned earlier, it will have 4-6 external bgp peers per router. Handle full bgp tables. Should be capable of policy based routing.
I am looking to implement 25 Cisco 3750 switches with IPBASE image at the edge, across many cabinets. I understand I am limited to EIGRP Stub on the 3750 switches (with IPBase) and cannot acheive funding to upgrade to IPServices. Though I am not fully aware on the limitations, in terms of what I am trying to acheive.
Broadly speaking I want to install 2 x 3750 switches at the edge, with point-to-point links to two 6500 core switches (at the data centre) and then have HSRP interfaces on the 3750's, tracking the up links to the core switches. I am presuming this will be the best solution to ensure reliability.My 6500 switches run EIGRP and have many VLANs and other L3 networks advertised, which will need advertising to the 3750 switches. I would be looking to advertise two or three HSRP networks on the 3750 switches, up to the core switches.At the moment, the entire network is Layer 2 (VLANS + STP).
how to configure EIGRP across the 3750 switches and 6500 switches to allow for the 3750's to see the whole network and also advertise back up it's directly connected (HSRP) networks to the core. At the moment, after configuration, none of the switches see each other as EIGRP neighbours but can ping the L3 addresses on each end.
We are replacing a DS3 Internet connection with a 100 Mbps fastE connection from a Tier 1 Provider. I currently have a Cisco 7204VXR with 512 Mb DRAM and 128 Mb of Flash and two 10/100 ports that is connected to the DS3. I also have a 3845 with 1 Gb of DRAM and 256 Mb of Flash with two 10/100/1000 ports available.
We are currently running BGP, below is the summary

How to successfully implement OER w/ NAT? I will have an 1841 with the 4-port EtherSwitch module that will have 3 cable modems connected and utilizing cisco's OER to utilize all 3 links for outbound Internet traffic. However, I am concerned about NAT. The only other interface used on the 1841 will be the connection to the local LAN (inside). I'm thinking this will require a loopback, but I'm not finding anything on CCO to back me up. Is it possible to just let the CMs do NAT? 1 CM is a static IP and the 2 others are DHCP.

i have a problem with a cisco cat. 4507 edge switch as when i have a login ssh session to the switch the supervisor engine restart and the redundant Sup. engine becomes the active and so on this problem mainly happen when i have multible SSH session to the switch and it happened very rarely with a single ssh login

Today I'm going to be re-organzing my network, kind of and I just wanted to get a second opinon. Right now I have an ASA 5510 and a Cisco 2911 and a Cisco 2960 (and I have two more 2911s and 2960s that handles our phone network).
Router 2911 is on the edge Gi0/0 has the public IP and Gi0/1 is not used and then I have 5 individual VLANs (Gi0/1.100, 1.200, 1.300, 1.400, 1.500) VLAN 100 is our internal network 10.10.18.1/24 (router is 10.10.18.1)And the 2960 is used for swichport access, the ASA is on the side and only used as a VPN.
What I want to do is put the ASA on the edge so I can dump all the access-lists and everything then 2911 will only be used to route the traffic. Now I know I will have to reconfigure the VPN, which isn't a problem. My question is when putting the ASA on the edge do I just put the public IP on the ASA's e0/0 and then plug the 2911 into the e0/1 of the ASA and give the Gi0/0 of the 2911 the ip address of 10.10.18.1 or do I just shut it down? The reason behind this is because I would actually like to use the ASA for more than just the VPN passthrough.
I have a very basic networking question If I have, say, 3750's (or any L3 switch, capable of routing) at the edge and a 4500 at the core, where should I route? At the edge? At the Core? Both?
View 4 Replies View RelatedI have a cisco 3560 switch set up as my edge router. It is working as my external demarc switch and edge router. It is sitting between the ISP's switch and my ASA firewall. It's a very basic configuration with port 1 set up with a fixed ip and switchport turned off which is connected to the ISP switch. VLAN2 is configured with an IP address and 3 ports, two of which go to different firewalls.
I found that I cannot ping a specific address from the inside interface (VLAN2), but I can from the outside interface Gig0/1. I have a few deny commands in an access list, but they don't apply to the network i'm trying to access, and I haven't had any other inaccessible networks otherwise.

most service providers in our country dont have 3G or 4G support,but all the same i bought an MR3420 router in the hopes that since my modem is listed,it would still connect even if on an EDGE/2G network like YU-Kenya.But this is not the case,the router does not recognize the modem i.e it says the modem is unplugged but when i look at the logs,it indicated it detected the modem but LTE was set to zero. providing a modem bin file for compatibility under EDGE/2G connection otherwise my router will be of no use to me.
