PPTP DHCP weirdness

RouterOS General
1

I have setup two rb532a routers (2.9.10) as a hotspot and pptp-server for windows clients. The pptp client’s and non-pptp client’s do dhcp OK.

I used the exact same commands on a third x86 MT router. The non-pptp client’s dchp OK, but when the pptp client’s get the dhcp info, they get the correct ip address (10.100.2.254), but the netmask is set to 255.255.255.255 and the gateway is set to the same as the client’s ip address (10.100.2.254). This leaves them unable to get anywhere. The dhcp-server knows that the gateway is 10.100.2.1, but it assigns the client address as the gateway instead.

I re-added the dhcp network settings and ip pools, but no difference.

Any idea why dhcp on 2.9.10 x86 would do this, but not 2.9.10 mips?

Any recommendations other than resetting the router config and starting from scratch?

Well, the problem was my own mis-managed firewall rules in the x86 routers. I deleted the masq action on the subnet of the pptp ip pools. I should have uploaded my config so someone could have pointed out my blindness.
