Hello All,
I have an issue with an ISR router i'm setting up on my home lab.
my ISP provides IP addresses on a vlan interface.
when my router is configured with this Dot1Q interface, it gets an IP from the ISP DHCP server.
when i configure NAT on the outside interface, (ip nat outside) i can no longer receive an IP from the DHCP server for that interface.
here are my configs:
outside interface:
interface GigabitEthernet0/0/0.35
description ISP_vlan_35
encapsulation dot1Q 35
ip address dhcp
ip nat outside
NAT configs:
ip nat inside source list 100 interface GigabitEthernet0/0/0.35 overload
ACL config:
access-list 100 permit ip any any
default route:
ip route 0.0.0.0 0.0.0.0 GigabitEthernet0/0/0.35 dhcp
if i get an IP address and configure NAT afterwards, i can get on the internet from internal devices... until the DHCP lease expires.
any ideas on why i'm not getting an IP when i configure NAT-Outside?
thanks in advances for your help and attemtion to my question
