[-- Attachment #1 --] I would appreciate any help with this issue: I'm using ipfw on two machines, both running FreeBSD 4.5 RELEASE. At both machines the following rules apply: ipfw add pass tcp from A to B 22 ipfw add pass tcp form B to A 22 A and B being the respective IP addresses of the machines! Surprisingly, when I tried to log from each of the machines into the other, the ipfw wouldn't pass any tcp through. The login format is as per usual: ssh username@A ssh usernamer@B Thanks in anticipation, Adam ______________________________________ Scanned and protected by Inflex http://pldaniels.com/inflex [-- Attachment #2 --] <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"> <HTML><HEAD> <META http-equiv=Content-Type content="text/html; charset=iso-8859-1"> <META content="MSHTML 6.00.2600.0" name=GENERATOR> <STYLE></STYLE> </HEAD> <BODY bgColor=#ffffff> <DIV><FONT face=Arial color=#0000ff> I would appreciate any help with this issue: <DIV><FONT face=Arial color=#0000ff></FONT> </DIV> <DIV><FONT face=Arial color=#0000ff>I'm using ipfw on two machines, both running FreeBSD 4.5 RELEASE.</FONT></DIV> <DIV><FONT face=Arial color=#0000ff>At both machines the following rules apply:</FONT></DIV> <DIV><FONT face=Arial color=#0000ff>ipfw add pass tcp from A to B 22</FONT></DIV> <DIV><FONT face=Arial color=#0000ff>ipfw add pass tcp form B to A 22</FONT></DIV> <DIV><FONT face=Arial color=#0000ff>A and B being the respective IP addresses of the machines!</FONT></DIV> <DIV><FONT face=Arial color=#0000ff></FONT> </DIV> <DIV><FONT face=Arial color=#0000ff>Surprisingly, when I tried to log from each of the machines into the other, the ipfw wouldn't pass any tcp through.</FONT></DIV> <DIV><FONT face=Arial color=#0000ff></FONT> </DIV> <DIV><FONT face=Arial color=#0000ff></FONT> </DIV> <DIV><FONT face=Arial color=#0000ff>The login format is as per usual:</FONT></DIV> <DIV><FONT face=Arial color=#0000ff></FONT> </DIV> <DIV><FONT face=Arial color=#0000ff>ssh <A href="mailto:username@A">username@A</A></FONT></DIV> <DIV><FONT face=Arial color=#0000ff>ssh <A href="mailto:usernamer@B">usernamer@B</A></FONT></DIV> <DIV><FONT face=Arial color=#0000ff></FONT> </DIV> <DIV><FONT face=Arial color=#0000ff></FONT> </DIV> <DIV><FONT face=Arial color=#0000ff>Thanks in anticipation,</FONT></DIV> <DIV><FONT face=Arial color=#0000ff>Adam</FONT></DIV> <DIV> </DIV></FONT></DIV> <PRE> ______________________________________ Scanned and protected by Inflex http://pldaniels.com/inflex </pre> </BODY></HTML>
