Your reports are inconsistent. It's possible that your version of sed doesn't support the extended syntax -- but then it shouldn't ever have worked at all, not just missed a few things inside >< brackets.

Do you have GNU sed on your system? (gsed) Or perl?

I do have perl but I usually avoid perl as I m not at all familiar. Also perl is less likely to be on every server I use my scripts as compared to sed.

Code:
bash-3.2$ file /usr/xpg4/bin/sed
/usr/xpg4/bin/sed:      ELF 32-bit MSB executable SPARC Version 1, dynamically linked, stripped
bash-3.2$ which sed
/usr/bin/sed
bash-3.2$ gsed
bash: gsed: command not found

I tried using /usr/xpg4/bin/sed however, does not replace the strings either.

How about awk?
Code:
awk '{for (i=1; i<=NF; i++) if ($i==from) $i=to; print}' from=190.169.11.15 to=10.4.112.240 < proxy.log

Or
Code:
cat changefile
190.169.11.15 10.4.112.240

awk 'FILENAME!="-" {A[$1]=$2; next} {for (i=1; i<=NF; i++) if (A[$i]!="") $i=A[$i]; print}' changefile - < proxy.log

The (A[$i]!="") is clumsy and can consume extra memory but supports Solaris /bin/awk.
Better is ($i in A). Then Solaris needs nawk or /usr/xpg4/bin/awk
You can add more lines to changefile...
