I have an internet access through a 64 k leased line using NAT Technology.
The Nat configuration is as follows:
=====================================================
-------------------------------------------
ip nat pool Internet_Access 62.192.x.66 62.192.x.66 prefix-length 24
ip nat inside source list 7 pool Internet_access overload
ip classless
ip route 0.0.0.0 0.0.0.0 10.10.10.1
!
access-list 7 permit 192.168.100.0 0.0.0.255
---------------------------------------------------
All the serial and ethernet interfaces on the router have NAT inside except the serial interface which connects to the internet which has NAT outside
=====================================================
The routing configuration is as follows:
!
router rip
version 2
no validate-update-source
redistribute connected
network 10.0.0.0
network 62.0.0.0
network 128.1.0.0
network 192.168.10.0
network 192.168.30.0
network 192.168.40.0
network 192.168.100.0
network 192.168.116.0
network 192.168.240.0
neighbor 10.10.10.1
!
=====================================================
The interface which connects to the internet is 10.10.10.2 255.0.0.0
and on the ISP side is 10.10.10.1 255.0.0.0
I am able to ping and telnet 10.10.10.1 from a router successfully and when I Try traceroute from the router I am having this result:
Type escape sequence to abort.
Tracing the route to www.mtl.leland-mw.org (62.192.142.1)
1 10.10.10.1 32 msec 40 msec 56 msec
2 * * *
3 * * *
10.10.10.1 is the serial interface of my ISP router
I am not able to ping and telnet 10.10.10.1 from Dos successfully and when I Try tracert from Dos I am having this result:
192.168.100.207 reports:destination host unreachable
192.168.100.207 is my default gateway which is an ethernet interface which connects my hub.
=====================================================
I am unable to brouse the Internet. I am not sure whether this is my Problem os the ISP problem from these statistics? Please help

Hello,
can you post your full configuration ?

there is no route back to the address you are using for nat from the router after the 10.10.10.1 router .

Dear dmalamba,
first of all I suppose there is no such a need to force you to translate every serial and Ethernet interfaces address (why put NAT inside to any int other than your 192.168.100.207-ethernet?). Secondly, how does your router "know" the real ip address 62.192.x.66? Thirdly, since your ISP is connected to you via a private subnet (10.10.10.0/30 I suppose), they also should use NAT... do they really? Any answers?
