Re: [help] 851W and ISP DHCP
Sailing_Nut,
Replace ACL 102 under WAN interface with ACL 101 and see if it works. Here is the step
configure terminal
interface FastEthernet4
no ip access-group 102 in
ip access-group 101 in
end
copy running-config startup-config |

| Unfortunately no luck with switching the ACL.
If you think I would be best defaulting the router and starting again, I can do that. I've been thrashing about with SDM and the command line and it's possible that I've got some built up junk that's messing things up.
If I rebuild, I think it would be best to stay away from SDM because it seems to do lots of things that one might not intend. I'll just need some guidance in building the firewall rules.
Thanks! |

| After applying the ACL 101, did you reset the WAN interface?
Something like shut/no shut or reload the router would do.
No need to wipe out the entire config ..... at least not yet .... 
By resetting the interface, the router will reinitialize DHCP session with your ISP. See if your router can have the IP address then. |

| I had previously used SDM to take the interface down and back up.
I just tried the shut / no shut and that did not seem to work either. But, just to be sure I'm doing it right. I enterd these commands:
configuration terminal
int fa4
shut
no shut
end
Did I get it right? |

| Yup, it was the right command ...
Btw, do you have Static IP plan with your ISP?
You may want to confirm with the ISP if they use a system that lock down MAC address into their system. When they do, then you need to confirm that they have the correct WAN interface MAC address. Your correct WAN interface MAC address should be the one on the show interface FastEthernet4. |
