Hi,
I try to connect a Cisco router to both the Internet and the office HQ. Both
connections assign a dynamic IP address when the connection i established.
The relevant part of the config (Running 11.3(9):
ip
subnet-zero
ip nat inside source list 1 interface BRI0
overload
isdn switch-type
basic-net3
!
!
interface
Ethernet0
ip address 192.168.165.100
255.255.255.0
ip nat
inside
!
interface
BRI0
ip address
negotiated
ip nat
outside
encapsulation
ppp
dialer pool-member
1
ppp authentication chap pap
callin
!
interface Dialer1
description *** Connected to HQ
***
ip address
negotiated
ip nat
outside
encapsulation
ppp
load-interval
30
dialer
remote-name
dialer

callin
ppp pap sent-username password 7

interface
Dialer2
description *** Connected to ISP ***

ip
classless
ip route 0.0.0.0 0.0.0.0
Dialer2
ip route 132.229.0.0 255.255.0.0
Dialer1
!
access-list 1 permit
any
dialer-list 1 protocol ip
permit
If a packet for the HQ arrives, the ISDN-line will open, and the connection
will work. The same counts for a packet to HQ, but with one link up, the
other won't work. Does anyone have a clue how to solve this?
I think the combination with NAT and negotiated IP address is the problem.
With fixed addresses it'll work, but unfortunately I can get only 1
IP-address fixed (no, not the HQ-one, not within a reasonable timeframe :*(
Does anyone knows a way to solve/workaround this?
TIA!
Marcel
