ISP DHCP to Static ip.

Hello,

I have problems with PAT translation to a inside server. Somebody tell my that i can`t use a dynamic DHCP of the ISP to use the NAT/PAT transalation. If i configure a static ip-adres on the BVI interface then en can`t ping the ISP gateway. Is it possible to configure this a staic ip with ISP DHCP? Is is possible to use Dynamic ip for NAT/PAT?

I hope somebody can helping.

Thanks,

Bart

Re: ISP DHCP to Static ip.

I think you can use dynamic IP for Port Address Translation. For this you have to use command "set ip pat porthandler". Following link may help you

Hi,

please configure:

int eth0

no hold-queue 100 out

int atm0

no bridge group 1

no pvc 0/34

int atm0.1 point-to-point

bridge-group 1

pvc 0/34

encapsulation aal5snap

int bvi1

no ip access-list 100 in

no ip route 0.0.0.0 0.0.0.0 84.107.216.1

That should make things work.

I'm astonished about the other answer about an old series 700 non-ios router, now dead since almost 10 yers!!!

Hope this help. Please rate all useful posts using the scrollbox below!
