Cisco Routers :: RV220W Built-in DHCP Server Can't Save Class B IP Address Pool
Mar 28, 2012I was trying to set a DHCP pool with 127.16.0.0/16 with RV220W, however, RV220W UI can't save it. It displays "IP Address Range -"Step to reproduce: (it is 100% reproducible)
1. login into RV220W admin web
2. Create a VLAN, id 201
3. Go to "Multiple VLAN subnets", select the VLAN, click edit
4. Enter following info:
IP Address: 172.16.0.1
Subnet Mask: 255.255.0.0
DHCP Mode: DHCP Server
Domain Name: Cisco
Starting IP Address: 172.16.2.100
Ending IP Address: 172.16.10.254
Primary DNS Server: 172.16.0.1
Leave rest of settings with default value.
DNS proxy is enabled
5. Press Save button. The UI shows text "IP Address Range -".
Expected result: RV220W shall save the setting and make use of 172.16.0.0 subnet in IP pool. By the way, the error message "IP Address Range -" seems incompleteI tried same setting on netgear FVS318N (very similar settings to RV220W), it accepts 172.16.0.0/16 as DHCP IP pool and works.RV220W has great feature set meets my needs. Its UI is slow and sometime dashboard freezes, which I can live with comparing to features. But DHCP server IP pool can't be class B is huge limitation to me.

View 1 Replies View RelatedCisco Firewall :: ASA 8.4.3 Class C IP Addressing / Routing Subnet Design
Sep 25, 2012I am carving up an internet Class C for customer. This class C is used by 3 distinct QA, Corporate and Production firewalls. I want to carve up IP space so there is a /26 for each environment. The issue I have is the firewalls may need communication with each other via the public IP space. Currently I don’t have any L3 switches in between the firewalls and the edge internet router. So with subnetting, it would seem I need to push everything through the internet router for the intra-firewall communication.I would rather not push this traffic through the edge router, so I came up with an idea to allocate all firewall outside interface IP’s in the 4th (last remaining) /26. That way, I can allow firewalls to communicate over the primary interface IP’s, which will all be in the same subnet – without going through a routing “engine”/device.
For the actual environment subnets (NAT's on respective firewalls), I create a static route on the edge router pointing to each of the firewall’s primary IP’s for the respective environment routes (the first 3 - /26’s).This is still a beta design, but I have done this before on small scale when ISP gave me 2 subnets for example, assuming I was going to put a router in between the customer firewall and ISP. I would use the “routed subnet” on the ASA interface, and then pull the NAT’s from the other subnet. The ISP would have to add a static route directing the NAT subnet to the “routed subnet” correct IP - which would be the firewall outside interface primary IP.I recently found out that with ASA OS 8.4.3 and up, ASA will not proxy arp for IP’s not in its local interface subnet. This means the ISP/router will have to assign static ARP entries on the edge router. This can get messy after the first few NAT entries. So I am debating the design now. I think this kind of stuff going forward won’t be worthwhile with newer ASA 8.4.3 code.
How to communicate between different ASA’s, while still carving up the Class C into usable smaller subnets? The primary reason for doing this in the first place is to support routing on the edge router. I am thinking it might be time to ask for another Class C to do the routing functions, and keep the firewalls all at Layer 2 in one /24 - Class C?

Mar 13, 2012How to set up a home network with 2 routers, where R1 acts as the DHCP server and R2 is basically a switch, connected LAN to LAN and everything is on the same subnet. Currently I have a different setup:Both routers have the DHCP server enabled and I connect R2's WAN port to R1 LAN. Therefore I have 2 subnets. Now my special requirement is that R2 is a DD-WRT router, which establishes a VPN connection to StrongVPN, so that all internet traffic via R2 is encrypted and goes through the StrongVPN server. Now my question:If I change my router setup to the same subnet, meaning R2 connects LAN to R1 LAN and I disable DHCP server on R2, will R2 still be able to establish the VPN connection?

Changed 2nd router IP address to 192.168.1.2 static, disabled DHCP, added 1st router IP as default gateway, set subnet mask to same as 1st router. Problem occurs in next frame called 'Network Setup' it is requiring a 'router IP' & subnet mask again and will not accept either the 1st or 2nd router IP address - gives the "IP equals subnet please correct" error or "LAN & WAN IP addresses are identical.

Sep 25, 2012I have an issue with some traffic routing:
Machine A | Machine B (Win 2008 R2) | Machine C
Start: 192.168.5.9 > 192.168.5.5 (NIC 1) - 10.14.137.130 (NIC 2) > 10.14.137.128So the question is how do i get traffic from Machine A to Machine C. I've tried various 'Route ADD' cmds but no luck so far. So was hoping someone out there could shed some light for me?Machine B is a AD/DNS and can talk to the entire 10.14.137.x range but has no forwarders set up in DNS. And does not act as a AD/DNS server for the 10.14.137.x range. It fills these roles only for the 192.1668.5.x range.
Routers / Switches :: Network Subnet Range To Wide For Vpn?
Jun 23, 2011I have a supplier which i need to connect a site to site ipsec vpn connection to (from a draytek router). I have already done this on our main site with no problems using the local ip details of 192.168.1.0 and subnet 255.255.255.0 however i need to do the same on our DR site which uses the ip details of 10.1.0.0 and subnet of 255.255.0.0. Our supplier told me the 255.255.0.0 is already used at there end by a different customer so we are unable to connect the vpn and communicate (in theroy we can connect but our supplier cannot reply). We can setup a connection to another spare server on a different address using a different subnet but effectivly this would mean that communication would stop at that server and communcation to the overall network or specific server the supplier needs access to (on the 10.1.0.0 255.255.0.0 network) is not possible. I was thinking maybe an internal vpn server to server connection through win server may do it, 2 nic cards or routes in the server routing table but this all seems a bit messy. Our network consits of win 2003 and 2008 R2 servers and is basic network with modem-vpnfirewall-switch and devices on the internal network connecting to the switch.

Dec 13, 2011I am looking a old exercise I did last year about subnetting and I am wondering if is possible to subnet:
198.18.9.1 /22
I wrote down, last year, that:
16 bit are assigned to network
6 to subnet
10 to hosts
when actually I see a class C ip address with 10 bit assigned to hosts. So, how many bit do I have for network, subnet and hosts?

Sep 6, 2012Im having a (from google-fu) seemingly unique issue with load balancing. So for background, I am running the ACE 4710 device in "on a stick" mode, so I am using NAT and all that good stuff. I am also utilizing class maps and host header matching so I can save on IP space. [code]
Basically, as soon as I add that ACL_CLASS_beta.mainsite.com class map, all I get back from the ACE is RST packets and it comes back with an L7 LB Policy Miss.
It SEEMS like it should work, but it doesnt seem to like matching on those source addresses at all.

Jan 16, 2012I'm trying to configure a zone-based firewall on an SR520 and am confused about the 'not' criterion. The 'zone-design-guide' says (my stress): Class- maps define the traffic that the firewall selects for policy application. Layer 4 class-maps sort the traffic based on these criteria listed here. These criteria are specified using the match.where my intention is to let only LAN hosts with IPs in the range 192.168.1.1 to 192.168.1.7 out through the firewall. There may be an easier way of doing this which I'd be pleased to hear about. But, even if there is, I'd also be interested to know what I'm doing wrong in the above.
