I am removing the Split tunnel configuration on an 1811 router connected over a PPPOE connection. The tunnel is working but I am getting timeouts every 10 packets or so and there is severe latency. I am wondering if the dialer pool statements were tied to the NAT configuration that I removed? Below is the NAT statements I removed. The outside IP addresses are blocked out. I have also attached the configuration after making the changes.
ip nat pool POOL xxx.xxx.xxx.xxx
xxx.xxx.xxx.xxx prefix-length 20
ip nat inside source route-map nonat pool POOL overload.
