Hi, All!

Sorry for my bad english =)


I have a small network 10.15.0.0 /24

Cisco is a gateway and DHCP server for internal network.

ISP link is directly connected to fa4


I've been requested to configure PPTP server on this device for remote users


Config is below:


sh ver:

Cisco IOS Software, C850 Software (C850-ADVSECURITYK9-M), Version 12.4(4)T8, RELEASE SOFTWARE (fc3)

ROM: System Bootstrap, Version 12.3(8r)YI4, RELEASE SOFTWARE




config:

aaa new-model

!

!

aaa authentication login default local

aaa authentication ppp vpn local

aaa authorization console

aaa authorization exec default local

aaa authorization network vpn local

!


ip subnet-zero

ip dhcp excluded-address 10.15.0.1

ip dhcp excluded-address 10.15.0.2

!

ip dhcp pool DHCPPOOL

import all

network 10.15.0.0 255.255.255.0

default-router 10.15.0.1

dns-server 10.15.0.2 10.15.0.1 195.112.*.*

domain-name wr

lease 2

!

ip cef

ip domain name NAMETHERE

ip name-server 195.112.*.*

ip name-server 195.112.*.*

vpdn enable


username vpn password 0 test

username vpn aaa attribute list vpn




interface FastEthernet4

description WAN interface

ip address 195.112.*.* 255.255.255.0

ip nat outside

ip virtual-reassembly

duplex auto

speed auto

!

interface Virtual-Template1

ip unnumbered Vlan1

peer default ip address dhcp-pool DHCPPOOL

ppp authentication ms-chap

!

interface Vlan1

ip address 10.15.0.1 255.255.255.0

ip broadcast-address 10.15.0.255

ip nat inside

ip virtual-reassembly

!

ip default-gateway *.*.*.*

ip classless

ip route 0.0.0.0 0.0.0.0 *.*.*.*




Remote user's can connect to this network, but they obtain wrong tcp\ip parameters.




example:

testpptp - PPP:


DNS-suffix . . :

description . . . . . . . . . . . . : WAN (PPP/SLIP) Interface

physical address. . . . . . . . . : 00-53-45-00-00-00

Dhcp enable. . . . . . . . . . . : no

IP-address . . . . . . . . . . . . : 10.15.0.19

Subnet Mask . . . . . . . . . . : 255.255.255.255

GateWay . . . . . . . . . . :

DNS-servers . . . . . . . . . . . : 195.112.*.* 195.112.*.*



So they obtain correct ip address, but incorrect DNS server, gateway, subnet mask.


And question is WHY? :)


I hope i wrote it correctly and clearly.

Thanks

Can you see the translation for GRE. Could you provide the details of sh ver, sh access-list and show log
