I'm having an issue with static NAT over an ISDN interface. Router won't dial.
the outside source addresses are natted to IP addresses from the local ethernet0 subnet
config is:
username xxxxxxx password 7 082814680E10304E46
isdn switch-type basic-net3
interface FastEthernet0
ip address 192.168.243.49 255.255.255.240
ip nat inside
no ip route-cache
speed auto
interface BRI0
no ip address
ip nat outside
encapsulation ppp
no ip route-cache
dialer pool-member 1
dialer pool-member 2
no snmp trap link-status
isdn switch-type basic-net3
no cdp enable
ppp authentication chap
interface Dialer1
description ****ISDN****
ip address 194.15.247.34 255.255.255.252
ip nat outside
encapsulation ppp
dialer pool 2
dialer remote-name xxxx
dialer idle-timeout 360
dialer string 00123123123123
dialer-group 1
no cdp enable
ppp authentication chap
ppp chap hostname xxxxx
ppp chap password 7 030D082D010614345
ip nat outside source static 172.27.34.53 192.168.243.53
ip nat outside source static 172.27.34.52 192.168.243.52
ip route 172.27.34.52 255.255.255.255 Dialer1
ip route 172.27.34.53 255.255.255.255 Dialer1
dialer-list 1 protocol ip permit
i'm sure its a problem with the NAT
SHOW IP NAT TRANS YIELDS:
Pro Inside global Inside local Outside local Outside global
--- --- --- 192.168.243.52 172.27.34.52
--- --- --- 192.168.243.53 172.27.34.53
which is correct.
the isdn does work as i can ping accross the dialer to the other end. The problem is when a user on the inside targets the NAT address, the router won't dial.
any ideas
regards
Andy
