DHCP address relay

Unanswered Question
Feb 26th, 2009

Hi all,

As of recent i have put in these cisco 1812's and configuring them so they have remote vpn access enabled. For this i configure a dhcp relay on the internal interface and then use the "crypto isakmp client configuration group [NAME]" command to configure the DHCP settings.

The last cisco i tried was an 1841 and it did not have the DHCP command, so i am unable to set the giaddr or DHCP server. Does anyone have any idea why i cannot use these commands ?

(I have disabled DHCP server as well on the router)

Regards,

Nathan

I have this problem too.

Try this DHCP configuration.

router>enable

router#config t

router(config)#service dhcp or router(config)#ip bootp

router(config)# ip dhcp pool TEST

router(dhcp-config)# network X.X.X.X Y.Y.Y.Y ( ip address and subnet

mask that the LAN will use )

router(dhcp-config)# dns-server {ip of dns1} {ip of dns 2}

router(dhcp-config)# default-router Z.Z.Z.Z ( internalip address of the router)

router(dhcp-config)#ctrl-z <----to exit

router(dhcp-config)#ip dhcp excluded-address

To use a remote dhcp server

router>enable

router#config t

router(config)# ip helper-address x.x.x.x <---- ip address of the

remote dhcp server router(config)#exit
