The outside interface recieves the IP address over pppoe. Normaly you don't need to configure a fix IP with pppoe, but for any reason I don't recieve an IP address until I hardcode it on the ASA. Then when I reboot the ASA the IP address of the outside interface is lost.Further, I'm not able to change the subnetmask, it changes always to a host subnetmask. Has someone already made the same experience? See below the configuration of the outside interface and the pppoe statements.
pppoe client vpdn group any
ip address XXX.XXX.XXX.XXX 255.255.255.255 pppoe setroute
I figured out now the bug. When I enter the IP address at the outside interface with for example a /30 subnetmask, it takes this command, but for any reason it changes the mask to /32 when you have a look in the running config a few seconds after you entered the command.
See this below:
ciscoasa(config-if)# ip address 184.108.40.206 255.255.255.252 pppoe setroutPPPoE is already enabled on outside interface - now clearing
ciscoasa(config-if)# sh int e0/0
Interface Ethernet0/0 "outside", is up, line protocol is up
We have configured the outside and inside Interface with official ipv6 adresses, set a default route on outside Interface to our router, we also have definied a rule , which also gets hits, to permit tcp from inside Interface to any6.
In Syslog I also se...
