Ok all.
First off, thanks again for all the help you've offered thus far. That
being said, I'm having a problem with variables in a function. The
code I'm having a problem with is:
setup_loopback () {
${fwcmd} add ${rulenum1} pass all from any to any via lo0;
${rulenum1}=`expr $rulenum1 + 50`
${fwcmd} add ${rulenum1} deny all from any to 127.0.0.0/8;
${rulenum1}=`expr $rulenum1 + 50`
${fwcmd} add ${rulenum1} deny ip from 127.0.0.0/8 to any;
${rulenum1}=`expr $rulenum1 + 50`
}
The output of this, when run, is:
00050 allow ip from any to any via lo0
50=100: not found
00050 deny ip from any to 127.0.0.0/8
50=100: not found
00050 deny ip from 127.0.0.0/8 to any
50=100: not found
This tells me that it's doing the math correctly, but it's not
reassigning the calculated value back to the variable.
Any pointers?
