Internet rounter config problem

Hi, I've got a Cisco 1750 that I'm replacing an old Intel router with.

I can get the router up and am able to ping the ISP from the router, so the connection looks good. My problem is, I can't get any host connectivity through the router! No web browing or anything. What am I doing wrong!!

I have a bank of 6 public addresses that 2 of which are a nat pool and

3 of them are 1 to 1 static mappings for specific internal hosts (mail, web, citrix)

I'm trying to get all this down, but its confusing sometimes. I'd REALLY appreciate a push in the right direction.

config:

Current configuration: ! version 12.0 service timestamps debug uptime service timestamps log uptime no service password-encryption ! hostname internet

! memory-size iomem 25 ip subnet-zero ! ! interface Serial0 description internet connection bandwidth 1536 ip address xxx.xxx.xx.62 255.255.255.252 no ip directed-broadcast encapsulation frame-relay IETF no fair-queue frame-relay map ip xxx.xxx.xx.61 16 ! interface FastEthernet0 bandwidth 100000 ip address 192.168.1.250 255.255.255.0 no ip directed-broadcast full-duplex ! router rip version 2 network 192.168.1.0 ! ip nat pool nat-pool xxx.xxx.xx.69 xxx.xxx.xx.70 netmask

Yes, I missed the ip nat inside/outside statements. I put the access-list 1 in, I'll see what happens. Heres the updated info: interface Serial0 description internet connection bandwidth 1536 ip address xxx.xxx.xx.62 255.255.255.252 no ip directed-broadcast ip nat outside encapsulation frame-relay IETF no fair-queue frame-relay map ip xxx.xxx.xx.61 16 ! interface FastEthernet0 bandwidth 100000 ip address 192.168.1.250 255.255.255.0 no ip directed-broadcast ip nat inside full-duplex

! ip nat pool nat-pool xxx.xxx.xx.69 xxx.xxx.xx.70 netmask

255.255.255.248 ip nat inside source list 1 pool nat-pool overload ip nat inside source route-map internet interface Serial0 overload ip nat inside source static 192.168.1.206 xxx.xxx.xx.65 ip nat inside source static 192.168.1.208 xxx.xxx.xx.66 ip nat inside source static 192.168.1.211 xxx.xxx.xx.67 ip classless ip route 0.0.0.0 0.0.0.0 xxx.xxx.xx.61 ip route 10.1.10.0 255.255.255.0 192.168.1.254 no ip http server ! access-list 1 permit 192.168.1.0 0.0.0.255 !

Thank you so much!!!! Like I said, I'm still learning.

Your NAT isn't set up correctly. Firstly you will need to add NAT to the interfaces.

interface Serial0 ip nat outside ! interface FastEthernet0 ip nat inside

You also have this ...

ip nat pool nat-pool xxx.xxx.xx.69 xxx.xxx.xx.70 netmask

... but you haven't created the access list to match the nat statement.

access-list 1 permit 192.168.1.0 0.0.0.255 any

You should also turn RIP off as well if it's not needed.
