On the AT&T DSL modem Ethernet interface you mention that the IP address is 22.214.171.124/29 and the Cisco VPN 3002 clients Ethernet interface has an IP address of 126.96.36.199/29.
Using the /29 mask of 255.255.255.248 is the IP address of the DSL modem not the broadcast IP address of that subnet and the IP address assigned to the Cisco VPN 3002 not the subnet number of the next subnet? as the /29 mask provides a subnet block size of 8.
So the subnets would be
I don't understand how these IP addresses are assigned to interfaces, or am I missing something?
Thannk you for your replies. Michael is right, I didn't use the real IPs and should have added a note for this when I posted the initial question.
I am out for vacation for this week so I am unable to do the testings. I am new to Cisco & networking so I have a few questions and hoope you can help me with:
1). Why should I enable NAT? Shouldn't NAT be automatically configured so traffics initiated from inside the network can be routed out to the Internet? If I need to configure a Cisco router, say 2610, do I need to enable NAT too? and should I always do this?
1.5). Should I enable NAT, in this case, in the Cisco VPN 3002 device?
2). Is there a general rule when I should add a "default route" in this format: "ip route 0.0.0.0 0.0.0.0 188.8.131.52" ? Where is default route normally put at - in the gateway, or a another router/host behind the gateway?
3). the reason I use VPN 3002 in this case is becasue I need to set up a Cisco WiFI AP. I got this VPN 3002 free from a friend so I don't have to invest on buying a router or build a software-based routing host. Is VPN 3002 capable of routing at all? I am not using it to connect to a VPN Concentrator at all. I am leaving it as a stand-alone unit serving for routing purpose only. Am I making a silly move here?
