Hi All ,
I have S2S tunnel established between Customer HO to our development center , Inside interface of my firewall is connected to an L3 switch , In this L3 switch , I have 2 ,No's of SVI Vlan defined ,Frist VLAN 10 user ll get IP address from local DHCP server connected to L3 switch , another VLAN 20 must need to get IP address from Customer HO DHCP server over VPN tunnel .
On the L3 switch SVI second VLAN 20 i have helper address configured 10.10.40.10 , so that my DHCP message will be unicast message from this VLAN interface .IP helper address is DHCP server IP address (10.10.40.10) of remote location .
Does IPSec VPN tunnel will pass unicast DHCP message to customer HO DHCP server via IPsec VPN tunnel ???.
how to achieve this DHCP IP assigment over here ?? if have connected my VLAN 20 directly to ASA inside interface , i can use DHCP relay configuration . but over here i am sending DHCP message as unicast DHCP message from my l3 switch to firewall inside interface . Does VPN tunnel support for DHCP traffic ?? or VPN tunnel does not support of dhcp traffic .???.
switch (vlan10 , vlan20) ---> ASA----->internet----> ASA----> DHCP server
HTH
