Hi,
I have a PIX515E, 5.3(2). I applied access-lists to permit only gre protocol between two stations (one from LAN, one from DMZ int) and it's not working, but when I allow only ip traffic it's working. There is no NAT from LAN to DMZ.
The same access-lists I applied on Cisco router and they were working, gre was passing, so everything was the same, except instead of pix I had router. Is there something else I must do on PIX? Or maybe upgrade to newer version? Any help is appreciated very much...
Thanks, Ivana
