Wed May 24 14:41:32 EDT 2000 Thank you for the quick reply. My alias.log file really did not help much. All it had were lines like the following: file: /var/log/alias.log icmp=0, udp=1, tcp=4, frag_id=0 frag_ptr=0 / tot=5 (sock=0) icmp=0, udp=1, tcp=3, frag_id=0 frag_ptr=0 / tot=4 (sock=0) icmp=0, udp=2, tcp=3, frag_id=0 frag_ptr=0 / tot=5 (sock=0) icmp=0, udp=1, tcp=3, frag_id=0 frag_ptr=0 / tot=4 (sock=0) icmp=0, udp=1, tcp=4, frag_id=0 frag_ptr=0 / tot=5 (sock=0) icmp=0, udp=2, tcp=4, frag_id=0 frag_ptr=0 / tot=6 (sock=0) icmp=0, udp=2, tcp=3, frag_id=0 frag_ptr=0 / tot=5 (sock=0) icmp=0, udp=2, tcp=4, frag_id=0 frag_ptr=0 / tot=6 (sock=0) icmp=0, udp=2, tcp=3, frag_id=0 frag_ptr=0 / tot=5 (sock=0) icmp=0, udp=1, tcp=3, frag_id=0 frag_ptr=0 / tot=4 (sock=0) icmp=0, udp=2, tcp=3, frag_id=0 frag_ptr=0 / tot=5 (sock=0) icmp=0, udp=3, tcp=3, frag_id=0 frag_ptr=0 / tot=6 (sock=0) icmp=0, udp=4, tcp=3, frag_id=0 frag_ptr=0 / tot=7 (sock=0) icmp=0, udp=4, tcp=4, frag_id=0 frag_ptr=0 / tot=8 (sock=0) icmp=0, udp=5, tcp=4, frag_id=0 frag_ptr=0 / tot=9 (sock=0) icmp=0, udp=6, tcp=4, frag_id=0 frag_ptr=0 / tot=10 (sock=0) icmp=0, udp=7, tcp=4, frag_id=0 frag_ptr=0 / tot=11 (sock=0) icmp=0, udp=8, tcp=4, frag_id=0 frag_ptr=0 / tot=12 (sock=0) icmp=0, udp=9, tcp=4, frag_id=0 frag_ptr=0 / tot=13 (sock=0) icmp=0, udp=10, tcp=4, frag_id=0 frag_ptr=0 / tot=14 (sock=0) icmp=0, udp=11, tcp=4, frag_id=0 frag_ptr=0 / tot=15 (sock=0) icmp=0, udp=12, tcp=4, frag_id=0 frag_ptr=0 / tot=16 (sock=0) ..... etc. I know that doesn't help much. I was mainly worried that I had something wrong in m ppp.conf. Do I need a special section for the nat area. Or does the file look ok? Thanks again for your help. Andrew.
