Help With Cidr Block
-
Hello,
I was wondering if anyone could help me with this issue.
I recently recieved a CIDR block from my isp cox cable. I have the information below
wan ip: 70.177.0.29 - N/A - routed
Gateway: 70.177.0.17
Netmask: 255.255.255.240
Primary Name server: 68.105.28.16
Secondary Name server: 68.105.29.16Subnet 184.188.172.64/26 - routed
NetMask 255.255.255.192
Number of hosts 61
Suggested Default Gateway: 184.188.172.65
First Useable 184.188.172.66
Last Useable 184.188.172.126
Broadcast 184.188.172.127Here is my setup. –
WAN is: 70.177.0.29 with a gateway of 70.177.0.17
Lan is: 172.16.10.254 or should i make the lan 172.16.10.1 the mask is /24.
i have an ipsec connection that runs over the lan to multiple locations, so i need the lan to be seperate. -- as i have about 30 computers on the lan that recieve the public ip of 70.177.0.29
OPT2 Interface is address is 184.188.172.65 /26. which is the default gateway, i was told by cox to put that there. I have no default gateway setup on the OPT2.
I have also setup a dhcp server in the range 184.188.172.66 to 184.188.172.66.80 -- all servers in the OPT2 get an ip address. I get errors though, that says no dns server can be found. I cannot ping anything outside like google.com. All i get on the servers is no dns server available. - I asked cox 4 times if the ip's are routable. they say yes everytime. --
I tried firewall rules to allow traffic to the 70.177.0.29 and i tried static routes. -
I appreciate anyone's help on this, or what else i could try.
thank you.

here is an update.
I can now ping out. - however, the ip is 70.177.0.29 the static ip for the wan. when i try Virtual ip, i get nothing. - I cant use the lan, as i have voip phones on there, that requrie an ipsec connection to a remote switch, and they need a public ip address. - So i thought i try a dmz, or use the opt2 as the cidr block.
thanks,
