Bill -
On Leigh's config, there is the Interface Vlan address on the switch
which I didn't notice on your config. You may want to check this.

Hey Bill,
I just cobbled this together using a 3750 and an 1841.
Test 1 config:-
3750
int f1/0/15
sw trunk enc do
sw trunk nat 234
sw mo trunk
int vlan 6
ip address 6.0.0.1 255.255.255.0
1841
int f0/1.6
enc dot 6
ip add 6.0.0.254 255.255.255.0
int f0/1.234
enc dot 234 nat
ip add 6.234.0.254 255.255.255.0
Test 2 config:-
3750
int f1/0/15
sw trunk enc do
sw trunk nat 234
sw mo trunk
no int vlan 6
int vlan 234
ip address 6.234.0.1 255.255.255.0
1841
int f0/1.6
enc dot 6
ip add 6.0.0.254 255.255.255.0
int f0/1.234
enc dot 234 nat
ip add 6.234.0.254 255.255.255.0
And it, erm, worked with no problems.. I did pings from the switch to
the .245 addresses.
It's odd that you're getting encapsulation errors - that's when it's got
the L3 address, but can't find the L2. From what I can see, your config
is sweet, might be worth grbbing a coffee, clearing the trunk config and
rebooting the sods!
