1811 Load Balancing (E0 DHCP/E1 Static) NAT not working when using E1

Hello,

I have question similar to this but having a NAT issue when going to the E1 link.  Here is my config.  Also I have configured SLA, and I have this very similar confiig at another site but both links static and working fine.  The reason I question NAT is because in dual mode the VPN Tunnel works fine.  If I move from one link to another it works fine.  But when going outside (internet surfing) it does not work with the E1.   If I flip to use E1 i still have the problem only when I connect E0 and shutdown the interface E1 everything is ok.  When I show nat translations it is working on E0, but not E1.  Can anyone help?

FYI: I have removed stuff from  the config,  Crypto, DNS, DHCP, etc...

Are you filtering traffic via ACL 108? Look in the log since you are logging all denied packets, see if this is causing the problem.

Hi,
Thank you for the reply and suggestion.  I have checked and nothing filtering the traffic also I completely removed the ACL to have the interface wide open and the issue is still there.  

NAT enteries show 172.0.0.1 at times when trying that interface.   I wondered if it would be a cost issue on the link one static and one DHCP.  More likely a NAT.  Not sure why this config on another site I have except that both links are static.  This is why I question the link type but things point to NAT.  It is as if NAT overload is not working when it goes through that interface.

Thanks..

In case anyone is wondering I solved my problem.  Has to do with the IP route on E0 (DHCP).  I use the following statement:
ip route 0.0.0.0 0.0.0.0 fastethernet 0

Which worked fine and does work until I introduced a second external link.  I changed the ip route to the following:
ip route 0.0.0.0 0.0.0.0 dhcp

now both links work correctly and load balance.
:)
