Maybe dhcp proxy doesn't work with pw-he, or there's any bug or something?
it's okay in this scenario:
int PW-Ether2100.2100
mtu 1560
ipv4 address 10.255.255.1 255.255.255.0

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 10.255.255.100, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 2/3/6 ms
what i'm missing?
