pptp and vlan

Sun Jul 17, 2005 5:07 pm

I try to connect to my intranet using mt pptp server feature. My intranet interface is vlan. I can succesfully connect with my pptp client and obtain ip address. But then I can't ping any host on intranet, only mikrotik repsonds.
I've tried with setting proxy-arp on intranet interface (ethernet and vlan) but that didn't help.

Thanks in advance
Piotr

piotr,

Proxy-ARP is only needed if the IP address you're assigning to the PPTP client
overlaps with your internal network.

It's hard to tell what causes your problems without seeing your router configuration.
In any case, it should not matter that your internal network is on a VLAN.

Actually mt pptp client address overlaps with internal network. I wonder if I should set proxy-arp on ethernet or vlan interface , or both

If the IP addresses of your internal network are assigned to the VLAN interface,
then you only need proxy-arp on the VLAN interface and not on the physical ethernet interface.
