I have a chainstay protector wrapped all around the chainstay.

Will this affect the rear-derailleur gear cable which on my bike is externally routed?

  • How thick is this chainstay protector? Usually the cables have 1 or 2mm distance to the frame. So a thin protector or velcro strap might just fit under them. You can also make a perfectly fine chainstay protector out of a piece of old road bike tyre or inner tube and some cable ties.

  • Some protectors are stick-on and cover the upper half of the stay only. It's quite sufficient as the chain is most likely to strike there.

No. Your shifter cable will be separated from the chainstay by at least the thickness of the cable-housing wall, plus the thickness of the cable-stop wall. Unless you've got an unusually thick chainstay protector, it will be thinner than that. But you can eyeball it and see if it is interfering.

I use helicopter tape, which is less than 1 mm thick.
