This then connects to a pix 506e but the 1721 has been</P><P>configured with public ip's on the wan's (each ip is from a different</P><P>range) they are then nated on the fa to a private ip.</P><P></P><P>My problem - is that the pix 506e has a public ip and is configured to</P><P>deal with various operations which need a public ip. So the fa int on</P><P>the router needs to have a public ip and no nat.</P><P></P><P>someone has suggested virtual int's on both pix and router ??</P><P></P><P>is this possible ?</P><P></P><P>Many Thanks</P><P></P><P>Alex</P><P></P><P>ps Ive posted the config from the router</P><P></P><P> </P><P></P> Mon, 11 Mar 2019 11:12:26 GMT https://community.cisco.com/t5/network-security/pix-506e-1721-connection-problem/m-p/876749#M969237 handley88 2019-03-11T11:12:26Z Re: Pix 506e - 1721 connection problem https://community.cisco.com/t5/network-security/pix-506e-1721-connection-problem/m-p/876750#M969238 <HTML><HEAD></HEAD><BODY><P>It will be better if you do NAT on PIX and not on the router.This way you can put the fa interface of router on a public ip address and connect this to the PIX.
