16:45 linkdown: pfctl -k 88.217.34.98
16:45 linkup: myaddr=82.135.87.233
16:48 dns-request with 88.217.34.98 as source address to 212.18.0.5

our DNS queries from internal servers are still sent with the old 
dynamic address as source address
where a local dig on the pf-box uses the new dynamic address.

Any suggestions where to search?

Thanks
Reinhard
