I recently bought a 3845 off ebay to replace my 3745
on my 3745 I used 3x NME-16ES-1G-p for intervlan routing and had the full ac+inline power setup so I was able to power my AP via POE without a injector (and one NM-1GE for connection to a D3 cable modem)
anyway using the same version of IOS I can't seem to get NAT to work, even thoguht the config is nearly the same
on the 3845 I don't have a need for the NM-1GE which was Gi 2/0 so on the 3845 gi0/0 is the wan interface
heres the ver and config

Ricky,
Can you please remove the secondary IP addresses from your Gi0/0 interface, then do clear ip nat translation * and try the traceroute again? You should not need to have the secondary IP addresses configured on your interface just because you are translating into them; the router is smart enough to create ProxyARP entries on behalf of addresses in the pools. I would like to remove all parts of the configuration that may interfere with the proper straightforward operation of NAT and routing.
Thank you!
Best regards,
Peter

Hi Ricky,
Thanks for letting us know. I suspect that stuck ARP entries are behind the entire issue: after you replaced the 3745 with 3845, the SMC kept the old ARP entries for the IP addresses in the NAT pools, breaking the connectivity. Just a guess but that would be my first shot.
Best regards,
Peter
12-08-2013 12:30 PM
Ricky,
Your current 3745 configuration indeed does not show any signs of configuration trouble, and I see no reason why it should not work on the 3845. However, to troubleshoot the 3845 behavior, we would need to see its configuration after you transferred it from 3745. Also, the output from show ip nat translation and show ip nat statistics would be necessary to see if there is at least something happening in the NAT. Can you please provide this information?
Best regards,
Peter

Ricky,
Thank you for the additional data. What about the show ip nat translation and show ip nat statistics? They contain some vital data about the NAT, apart from others, whether at least some NAT translations have been created. Once again, though, the configuration appears to be correct.
I wonder - with this configuration, are you actually able to ping from your 3845 out to the internet? Can you ping the default gateway, or perhaps ping even farther? I am thinking of a remote possibility of your internet connection being tied to the MAC address of the 3745 router, preventing you from connecting the 3845 directly.
Best regards,
Peter

from the 3845 I can ping the internet but if I source the ping from anything but the wan interface it fails (only pasting part of nat trans as its very long)

Ricky,
The NAT obviously works - the entries are a clear proof.
I wonder: There seems to be a lot of entries created on behalf of the 10.0.2.5 station, with this station trying to 10.254.254.x on SNMP ports. Is this normal? The sequence of translation entries suggests that the station must have been very intense in generating that many requests and consuming quite a number of entries in your NAT table. That could account for some of the issues you are seeing.
My suggestion: let's verify whether the basic routing and very simple NAT works on your router. I suggest temporarily reworking one of your ACLs to allow NAT only from directly connected networks on your router (avoiding the 10.0.2.5 as that one seems to be aggressive at present), and seeing if the NAT works with this limited configuration. If it does, let's start adding the networks back.
Best regards,
Peter

Well I can't ping the internet from behind the router
ie can't ping 4.2.2.2 (Level3 anycast dns)
10.0.2.5 is my PRTG network monitor so I'll just stop it for now (maybe I forgot to update it when I switched from 10.254.254 to 10.255.255
12-08-2013 03:30 PM
ok after stopping my SNMP monitor heres the trans and stats

Ricky,
Even if your 10.0.2.5 is your PRTG monitor, there seems to be an issue in routing: why would the packets to 10.254.254.x be routed out to public internet? It does not make sense.
You say you can not ping the internet from behind the router. What would traceroute say? Where does the traceroute stop?
Best regards,
Peter

well 10.254.254.1 used to be an IP of my router and as 10.254.254.x is an unknown net it would send it to the gateway of last resort (guess I never updated it to point to 10.255.255.1 instead)
from a computer I can ping
10.0.2.1 (etherswitch vlan interface)
10.255.255.2 (etherswitch vlan interface pointing to the router
10.255.255.1 (router interface pointing to etherswitch)
10.254.254.0 (router loop back interface , proving that it's routing)
but not 75.148.235.38 (ISP gateway pointing to me)
heres the tracert
1 1 ms 2 ms 2 ms rlh-ethsw.rlh-domain.net [10.0.2.1]
2 <1 ms <1 ms <1 ms 10.255.255.1

Ricky,
Can you please remove the secondary IP addresses from your Gi0/0 interface, then do clear ip nat translation * and try the traceroute again? You should not need to have the secondary IP addresses configured on your interface just because you are translating into them; the router is smart enough to create ProxyARP entries on behalf of addresses in the pools. I would like to remove all parts of the configuration that may interfere with the proper straightforward operation of NAT and routing.
Thank you!
Best regards,
Peter

ok removed the secondaries but still can't ping from a computer

for testing I've now shutdown gi 1/0, 3/0 and 4/0
and changed acl 1 to include loopback1
and added ip nat inside on the loopback
I issued the follosing list of commands
int gi 1/0
shut
int gi 3/0
shut
int gi 4/0
shut
exit
no access-list 1
access-list 1 permit 10.0.2.0 0.0.0.255
access-list 1 permit 10.254.254.0 0.0.0.255
access-list 1 deny any
int loopback1
ip nat in
so this should prevent any more nat translations other than what should occur for a ping sourced from the loopback

oh man am I mad at comcast now
after hours of troubleshooting the router I just power cycled the cable modem (SMC D3 acting as a pure router) and now it works
seems like it didn't want to reply to my new router for anything but the 33 till I power cycled it.
