My 831 router aquires its address from comast via DHCP. I have applied an access list to the ethernet port it resides on. I am trying to figure out what I need to put in the access-list to allow comcasts DHCP server to contact my ethernet port.
I have used the following...
access-list 151 permit udp any any eq 67 log
access-list 151 permit udp any host 255.255.255.255 eq 67 log
HI, Although you have enabled the UDP on port eq 67, you are denying any IP traffic on the ethernet interface. SO although you are letting the router aquire the IP address, all IP traffic is getting denyed. Hence your router shall not respond to any IP traffic. I am sure, you see the drops on your debug.
Please apply access-list 151 permit ip any any. And it should start working.
Ok, this is the only thing I need in the access list since its the inbound access list on the Dialer interface, I am allowing all outbound traffic. Is there a specific command to make sure that the Dialer interface can broadcast UDP packets out of port 68?
