We changed over our internet connection to fibre, and started using our 501 pix for pppoe. The problem I am having is that the PPPoE appears to be working, however no computer on the network can access the internet.
From the PIX I can ping 4.2.2.2,
pixfirewall(config)# ping 4.2.2.2
4.2.2.2 response received -- 30ms
4.2.2.2 response received -- 20ms
4.2.2.2 response received -- 20ms
And from the PIX I can ping the computer I am trying to access to the Internet from:
pixfirewall(config)# ping 192.168.16.52
192.168.16.52 response received -- 0ms
192.168.16.52 response received -- 0ms
192.168.16.52 response received -- 0ms
However, from inside the network, I cannot ping the 4.2.2.2 address or get any internet access. Our VPN however, comes up and works fine. I am certain I am missing something very simple, can anyone please spot it in the below?

Hi Mark,
The config looks fine. When you changed the internet service have you cleared the 'arp' on PIX ( and any switch in between PIX and ISP) or reload the same? If you still experience issues, two things you can try (One change at a time)..
1. Disable http fixup
2. set outside mtu to 1500
Thx
