Problem with subnets

Hi We have a Cisco router that forward traffic from subnet A to subnet B. I am able to ping a windows host in subnet A from a linux host in subnet B, but not vice-versa.Here is the config on the router. Kindly post your comments. Thanks

Using 1165 out of 29688 bytes ! version 12.0 service timestamps debug uptime service timestamps log uptime service password-encryption ! hostname Corp-WAN ! enable secret 5 $1$Hfy0$HVtYn6SGr01RgJHPW33ZG. enable password 7 025701431B030C355946061400 ! ip subnet-zero ip name-server 141.155.0.68 ! ! ! ! interface FastEthernet0/0 ip address 192.168.11.253 255.255.255.0 no ip directed-broadcast ip nat inside ! interface Serial0/0 ip address 192.168.254.1 255.255.255.0 no ip directed-broadcast shutdown ! interface FastEthernet0/1 ip address 192.168.5.2 255.255.255.0 no ip directed-broadcast ip nat outside ! ip nat inside source list 2 interface FastEthernet0/1 overload ip nat inside source static 192.168.11.63 192.168.5.63 ip nat inside source static 192.168.11.13 192.168.5.13 ip nat inside source static 192.168.11.61 192.168.5.61 ip nat inside source static 192.168.11.58 192.168.5.58 ip classless ip route 0.0.0.0 0.0.0.0 192.168.5.1 no ip http server ! access-list 2 permit 192.168.11.0 0.0.0.255 ! line con 0 password 7 0055161E145E08121A2943430C login transport input none line aux 0 line vty 0 4 password 7 0055161E145E08121A2943430C login ! no scheduler allocate end

I have looked at your config and can find no reference to either subnet A or B.

Also - what is it that you /want/ to do with NAT?

The subnets are 192.168.5.0 and 192.168.11.0

I don't know. They were there before. I haven't added them.

Thanks

Here is some more info

I cannot ping 192.168.5.152 from any host on the subnet 192.168.11.0 I can ping 192.168.5.58 and 192.168.5.1 (gateway) from any host on the subnet 192.168.11.0

Very mysterious! Thanks for your kind help

Also I ran the arp -s 192.168.5.152 ethernet address on the windows host (192.168.11.xxx)

Thanks

So you can only ping the addresses that have static NAT entries? Sounds like the 192.168.11.0 machines don't have their default gateway set.

Sounds like there no nat translation yet. Try ping from 192.168.5.152 to

192.168.11.x first, then try ping 192.168.5.152 from 192.168.11.0 subnet.

What should be the default gateway? It's currently set to 192.168.11.253

Hi Doan There was no ping response from either side. I pinged 192.168.11.65 from 192.168.5.50. Similarly I pinged from 192.168.5.50 from

192.168.11.65. There was no response from either end

Hi Doan I can ping 192.168.5.58 from 192.168.11.65

I had to change the Gateway before everything became normal. I'm still having difficulty with the following: The adminnew.scholasticfundinggroup.com site's outside IP is

209.178.198.249 and inside it is 192.168.5.152

I am unable to view the site from a browser by typing

formatting link
I get the error Page Cannot Be Displayed.

The ping from dnsstuff.com works fine.

Please drop me a clue

Thanks

Can you view it by IP? https://192.168.5.152 and https://209.178.198.249 If so, that puts us on a dns related issue.
